MAIAC is a new algorithm that simultaneously retrieves aerosol and land bidirectional reflectance from MODIS data. It produces 1km resolution products including cloud mask, water vapor, aerosol optical thickness and fraction, and surface reflectance. The MAIAC algorithm fits blue band reflectance to retrieve aerosol optical thickness and coarse mode fraction using known surface reflectance in red and SWIR bands from previous retrievals. Validation shows MAIAC accuracy is generally similar to existing MOD04 algorithm over most global land areas. MAIAC provides an improved generic retrieval approach for aerosols and surface properties over both dark and bright land surfaces.

Atmospheric Correction Algorithm_IGARSS.pptx
This document describes three atmospheric correction algorithms for the Geostationary Ocean Color Imager (GOCI): the Standard NASA algorithm, the Spectral Shape Matching Method (SSMM), and the Sun-Glint Correction Algorithm (SGCA). It outlines the processing steps for each algorithm, including radiometric calibration, removal of Rayleigh and aerosol scattering, and derivation of remote sensing reflectance. Validation results show SSMM and SGCA provide reasonable matches to NASA standard processing of MODIS data, though all three GOCI algorithms could be improved by updating aerosol and ocean models. The document concludes the algorithms capture the essential ocean color measurement but would benefit from further refinement.
Vegetation monitoring using gpm data over mongolia
Vegetation mapping was conducted over Mongolian land using GPM/DPR satellite data. Backscatter signals from the Ku and Ka band radar were analyzed for different land cover types from 2014-2018. The signals showed incidence angle dependency and seasonal variations that correlated with land cover. Forest had higher backscatter than grass, while desert was lowest. Combining the Ku and Ka band signals using PCA clearly distinguished forest, grass and desert. This new remote sensing method using precipitation radar provides an effective way to continuously map and monitor vegetation dynamics for detecting land degradation.
Ronan Kerr: Exploring the Debris Disk Around Beta Pictoris
The document summarizes research analyzing nitrogen abundance in the debris disk around Beta Pictoris. It finds that modeling the data as having three components - interstellar medium, circumstellar disk, and wider component possibly from exocomets - provides the best fit. This points to preferential production rather than depletion as the cause of carbon and oxygen excess in the system. Future work could examine other molecular abundances and test how well the proposed dual-origin solution explains other elements.

Seismic data processing
This document outlines a simple seismic data processing workflow. It begins with acquiring field data and updating the geometry. Next steps include trace editing, amplitude recovery, and noise attenuation. Velocity analysis and normal moveout correction are then applied. Deconvolution and multiple attenuation are performed before migration. Post-migration involves stacking, filtering and amplitude scaling to produce the final processed seismic section. The goal of seismic processing is to produce high quality seismic data for geological interpretation and hydrocarbon exploration.

This study implements a Bayesian statistical framework to calibrate the SCOPE process-based simulator for simulating gross primary production (GPP) and top-of-canopy reflectance at a spruce flux tower site in the Czech Republic. Markov chain Monte Carlo simulation is used to quantify the uncertainty in SCOPE input parameters by comparing simulated and measured reflectance and GPP data. The results show the posterior parameter distributions have lower uncertainty than the prior distributions. Simulated half-hourly GPP over the growing season using maximum a posteriori parameter estimates matches the measured data. Future work will estimate seasonal parameter variations to improve GPP simulation accuracy.ESA SMOS (Soil Moisture and Ocean Salinity) Mission: Principles of Operation ...

This document summarizes a study using the CODALEMA experiment to analyze radio signals from air showers and identify properties of primary cosmic ray particles. It describes:
1) Analyzing time delays of radio signals compared to a plane wavefront hypothesis and finding systematic deviations, indicating the wavefront is curved.
2) Developing a model to reconstruct the emission center position based on fitting time delays to a parabolic function dependent on curvature radius and antenna distances.
3) Applying the model to 450 selected CODALEMA events and comparing reconstructed shower core positions to results from other models, finding consistency.Cloud vertical distribution in extratropical cyclones
1. CloudSat and CALIPSO satellite observations were used to analyze cloud vertical distributions across cold and warm fronts in extratropical cyclones in the Northern and Southern Hemispheres.
2. The observations showed low-level clouds everywhere across both cold and warm fronts, with high-level clouds ubiquitous across warm fronts and upright convection at warm fronts.
3. The GISS GCM model captured the general features but underestimated cloud fraction due to problems with moisture transport along and across fronts at the coarse resolution of the model. Improving moisture transport, including simulating slantwise convection, could help the model better represent extratropical cyclone clouds.

TITLE: Two cultures in high energy nuclear physics
Since the mid eighties a community originating within the Bevalac program at the LBNL has sought to achieve formation of a color-deconfined quark-gluon plasma in heavy ion (A-A) collisions using successively higher collision energies at the AGS, SPS, RHIC and now the LHC, emphasizing a flowing dense "partonic" medium as the principal phenomenon. During much of the same period the high energy physics (HEP) community studying elementary collisions (e-e, e-p, p-p) developed the modern theory of QCD, emphasizing dijet production (fragmentation of scattered partons to observable hadrons) as the principal (calculable) phenomenon. Initially it was assumed that the QGP phenomenon in most-central A-A collisions might be distinguished from the HEP dijet phenomenon in elementary collisions. However, strong overlaps in phenomenology have revealed significant conflicts between QGP and HEP "cultures," especially at RHIC and LHC energies. In this talk I review some of the history and contrast an assortment of experimental evidence and interpretations from the two cultures with suggested conflict resolution.

Atmospheric correction
This document discusses several approaches for atmospheric correction of remote sensing imagery:
1) Image-based methods like the dark pixel method and regression method estimate and remove atmospheric path radiance.
2) The empirical line method uses ground targets of known reflectance to model atmospheric effects.
3) Radiative transfer models precisely account for atmospheric conditions using numerical models like MODTRAN or 6S to convert pixel values to surface reflectance.
4) Relative correction methods normalize images without absolute calibration to surface reflectance. Atmospheric correction is needed to accurately analyze surface properties from remote sensing data and compare images acquired at different times or wavelengths.

Abstract:
Most ocean mapping surveys collect seafloor reflectivity (backscatter) along with bathymetry. While the consistency of bathymetry processed by commonly adopted algorithms is well established, surprisingly large variability is observed between the backscatter mosaics generated by different software packages when processing the same dataset. Such a situation severely limits the use of acoustic backscatter for quantitative analysis (e.g., monitoring seafloor change over time, or remote characterization of seafloor characteristics) and other commonly attempted tasks (e.g., merging mosaics from different origins).
Acoustic backscatter processing involves a complex sequence of steps, but inasmuch as commercial software packages mainly provide end-results, comparisons between those results offer little insight into where in the workflow the differences are generated. In addition, preliminary results of a software-inter-comparison working group have shown that each processing algorithm tends to adopt a distinct, unique workflow; this causes large disagreements even in the initial per-beam reflectivity values resulting from differences in basic operations such as snippet averaging and evaluation of flagged beams.
Far from ideal, this situation requires a clear shift from the past closed-source approach that has caused it. As such, the Open Backscatter Toolchain (OpenBST) project aims to provide the community with an open-source and metadata-rich modular implementation of a toolchain dedicated to acoustic backscatter processing. The long-term goal is not to create processing tools that would compete with available commercial solutions, but rather a set of open-source, community-vetted, reference algorithms usable by both developers and users for benchmarking their processing algorithms.
As a proof-of-concept, we present a prototype implementation with the key elements of the OpenBST approach:
• The data conversion from a native acquisition format (i.e., Kongsberg EM Series) to NetCDF-based data structures (components of the eXtensible Sounder Format) better suited to data exploration, processing and metadata coupling.
• A processing pipeline constituted by a set of interlocking, task-oriented tools simplifying their substitution with alternative approaches.
• The creation of final products (i.e., angular response curves and backscatter mosaics) capturing relevant acquisition and processing metadata.

This document summarizes the application of Marchenko imaging to a 2D ocean-bottom cable dataset from the North Sea Volve field. Marchenko redatuming estimates the full wavefield from virtual sources inside the medium using only surface reflection measurements and a smooth velocity model. The authors processed the field data to obtain an estimate of the reflection response required by Marchenko and used it to iteratively estimate focusing functions and retrieve up-going and down-going Green's functions. They performed target-oriented imaging at different depth levels using the redatumed reflection responses, revealing structures not visible in standard reverse-time migration. Marchenko imaging provides a way to obtain high-resolution images of target zones without needing detailed overburden models.

Radio signal from extensive air showers EAS studied by the CODALEMA experiment have been detected by means of the classic short fat antennas array working in a slave trigger mode by a particle scintillator array. It is shown that the radio shower wavefront is curved with respect to the plane wavefront hypothesis. Then a new fitting model (parabolic model) is proposed to fit the radio signal time delay distributions in an event-by-event basis. This model take into account this wavefront property and several shower geometry parameters such as: the existence of an apparent localised radio-emission source located at a distance Rc from the antenna array of and the
radio shower core on the ground. Comparison of the outputs from this model and other reconstruction models used in the same experiment show: 1)- That the radio shower core is shifted from the particle shower core in a statistic analysis approach. 2)- The capability of the radiodetection method to reconstruct the curvature radius
with a statistical error less than 50 g.cm−2 . Finally a preliminary study of the primary particle nature has been performed based on a comparison between data and Xmax distribution from Aires Monte-Carlo simulations for the same set of events.

It also outlines various dark matter candidate particles and the search strategies used, including direct detection experiments that have seen some positive hints of an annual modulation signal including DAMA/Libra and CoGeNT experiments, but are in tension with null results from Xenon, CDMS, and Edelweiss experiments. Collider searches for dark matter are also discussed.
Colored inversion
This document summarizes the steps to perform colored inversion (CI) on seismic data to obtain relative acoustic impedance values. CI involves: 1) Fitting a function to the log spectrum to model it, 2) Computing the difference between the modeled log spectrum and the seismic spectrum, 3) Converting the difference spectrum to an inversion operator, 4) Convolving the operator with the seismic data to obtain relative impedance values. As a quality control, the output impedance spectrum can be checked against the input log spectrum. The document provides code to implement this CI workflow using open-source Python libraries on a dataset from the Netherlands. CI produces informative relative impedance images to aid seismic interpretation.

The document discusses modeling efforts for the James Webb Space Telescope (JWST). Preliminary analysis indicated traditional third-order effects could cause performance issues. This leads to large detailed models with millions of elements to model the composite tubes. Rapid analysis cycles are used to minimize differences between the model and baseline, but the large models and short cycle time create demanding multi-disciplinary analysis.

It describes how the Simple Method of Atmospheric Correction was used to generate bottom-of-atmosphere reflectances for MODIS bands 1 through 19 and 26. Preliminary validation showed the uncertainty to be comparable to field measurements versus the standard MOD09 product. The new 19-band reflectance product and a validation report will be made available through the AusCover Data Portal by mid-2013.

PowerPoint Powerpoint
The document discusses modeling efforts for the James Webb Space Telescope (JWST). Preliminary analysis indicated traditional third-order effects could cause performance issues. This leads to large detailed models with millions of elements to model the composite tubes. Rapid analysis cycles are used to minimize differences between the model and baseline, but the large models and short cycle time create demanding multi-disciplinary analysis.

The document presents a methodology for prototyping an albedo algorithm for GOES-R using MODIS data. It uses an optimization approach that incorporates atmospheric radiative transfer modeling and land surface BRDF modeling to estimate surface albedo, spectral reflectance, and aerosol optical depth from MODIS TOA reflectance observations. The estimates were validated against ground measurements and other satellite products, showing good agreement within F&PS requirements for albedo accuracy and reflectance precision. Future work will include additional validations and improving diurnal albedo estimation using geostationary data.

General Coordinates Network: Harnessing Kafka for Real-Time Open Astronomy at...
Kafka has come to play an essential role in astronomy research. Particularly where black holes and neutron stars are involved, astronomers are increasingly seeking out the “time domain” and want to study explosive transients and variability. In response, observatories are increasingly adopting streaming technologies to send alerts to astronomers and to get their data to their science users in real time. In this talk, we will discuss architectural choices, challenges, and lessons learned in adapting Kafka for open science and open data. Our novel approach to OpenID Connect / OAuth2 in Kafka is designed to securely scale Kafka from access inside a single organization to access by the general public. We will present a case study of the General Coordinates Network (GCN), a public collaboration platform run by NASA for the astronomy research community to share alerts and rapid communications about high-energy, multi-messenger, and transient phenomena. Over the past 30 years, GCN has helped enable many seminal advances by disseminating observations, quantitative near-term predictions, requests for follow-up observations, and observing plans. GCN distributes alerts between space- and ground-based observatories, physics experiments, and thousands of working astronomers around the world.

This document presents a temporal filtering algorithm to reconstruct daily albedo series from the GLASS albedo product. The algorithm uses temporal correlations between neighboring days' albedo measurements to fill gaps and smooth fluctuations in the GLASS data. It calculates a weighted average of neighboring albedo values based on global a-priori albedo statistics from MODIS. Preliminary results show the algorithm can effectively fill gaps and smooth time series, though it may oversmooth at times. Further validation is still needed.

This document provides a preliminary study for the AROSAT satellite system. It discusses several key requirements including coverage area, resolution capabilities, duty cycle, onboard storage and download rates. It evaluates three potential spacecraft configurations and their impact on drag, solar array effectiveness and risk. Configuration #2 is preferred as it minimizes drag while having a simple solar array design. The document also examines how spacecraft altitude affects optical instrument parameters and the propulsion systems needed to compensate for atmospheric drag at different altitudes. Electric propulsion is recommended to enable lower orbits. Overall architectures are proposed for Configuration #2 that could meet requirements.

The document presents a method to retrieve properties of biomass burning aerosols using a combination of near-UV radiance measurements from the GOSAT/CAI sensor and near-IR polarimetry measurements from the PARASOL/POLDER sensor. The method involves estimating ground reflectance, atmospheric light, aerosol models using refractive indices, vertical aerosol profiles from CALIPSO data, and retrieving aerosol optical thickness, Angstrom exponent and single scattering albedo. Validation with AERONET data shows the retrieved aerosol optical thickness and Angstrom exponent values match partially. The method demonstrates the biomass burning aerosol properties vary over plumes with optical depth and Angstrom exponent

In the first part of the talk, we will present a sensitivity analysis of a novel sea ice model. neXtSIM is a continuous Lagrangian numerical model that uses an elastobrittle rheology to simulate the ice response to external forces. The response of the model is evaluated in terms of simulated ice drift distances from its initial position and from the mean position of the ensemble. The simulated ice drift is decomposed into advective and diffusive parts that are characterized separately both spatially and temporally and compared to what is obtained with a free-drift model, i.e. when the ice rheology does not play any role. Overall the large-scale response of neXtSIM is correlated to the ice thickness and the wind velocity fields while the free-drift model response is mostly correlated to the wind velocity pattern only. The seasonal variability of the model sensitivity shows the role of the ice compactness and rheology at both local and Arctic scales. Indeed, the ice drift simulated by neXtSIM in summer is close to the free-drift model, while the more compact and solid ice pack is showing a significantly different mechanical and drift behavior in winter. In contrast of the free-drift model, neXtSIM reproduces the sea ice Lagrangian diffusion regimes as found from observed trajectories. The forecast capability of neXtSIM is also evaluated using a large set of real buoy’s trajectories. We found that neXtSIM performs better in simulating sea ice drift, both in terms of forecast error and as a tool to assist search-and-rescue operations. Adaptive meshes, as the one used in neXtSIM, are used to model a wide variety of physical phenomena. Some of these models, in particular those of sea ice movement, use a remeshing process to remove and insert mesh points at various points in their evolution. This represents a challenge in developing compatible data assimilation schemes, as the dimension of the state space we wish to estimate can change over time when these remeshings occur.
In the second part of the talk, we highlight the challenges that such a modeling framework represents for data assimilation setup. We then describe a remeshing scheme for an adaptive mesh in one dimension. The development of advanced data assimilation methods that are appropriate for such a moving and remeshed grid is presented. Finally we discuss the extension of these techniques to two-dimensional models, like neXtSIM.TU2.L10 - NEXT-GENERATION GLOBAL PRECIPITATION PRODUCTS AND THEIR APPLICATIONS

The document summarizes the findings of NASA's VIIRS Land Team regarding the utility of VIIRS Land and Cryosphere EDRs to meet NASA's science requirements. It discusses several EDRs including land surface temperature, surface type, albedo, vegetation indices, and snow cover. For most products, continuity with MODIS is important but some changes or additions to the algorithms or additional products may be needed. Processing via NASA's Land PEATE could produce climate-quality VIIRS science products compatible with MODIS.

This document describes the workflow and results of a 3D geological modeling and volumetric assessment project. Key steps included: 1) constructing structural and stratigraphic frameworks from seismic and well data; 2) modeling facies distributions and petrophysical properties using geostatistics; and 3) estimating gas initially-in-place (GIIP) under different scenarios. Uncertainty was addressed through multiple realizations capturing variation in key parameters like gas-water contact depth, porosity, and water saturation. The analysis resulted in a range of GIIP estimates from 4.3 to 10.1 trillion standard cubic feet.
