The document summarizes the results of tomographic analysis of P-band SAR data collected over tropical and boreal forests. Three key findings are:
1) Analysis of BIOSAR 2007 data over a semi-boreal forest showed dominant scattering from the ground level in HH and VV polarizations, with weak scattering from the vegetation canopy. HV polarization showed stronger returns from the vegetation.
2) BIOSAR 2008 data over a boreal forest showed decreasing ground-to-volume ratio with increasing forest height, consistent with larger volumetric scattering structures in taller forests. Ground-to-volume ratio also depended on terrain slope for P-band but not L-band data.

FR4.L10.2: A MICROWAVE SCATTERING MODEL OF VEGETATED SURFACES BASED ON BOR/DD...
This document describes a microwave scattering model for vegetated surfaces being developed for NASA's Soil Moisture Active Passive (SMAP) mission. The model uses numerical solutions of Maxwell's equations to simulate scattering from both rough soil surfaces and vegetation volumes. It represents surfaces and vegetation as 3D "data cubes" that allow fast interpolation. Comparison to experimental data from a grassland site shows good agreement between modeled and measured backscatter values. The model will be used to retrieve soil moisture from SMAP radar measurements by inverting the physical scattering model.
Kernel-Based_Retrieval_of_Atmospheric_Profiles_from_IASI_Data.pdf
This document describes a study that used kernel-based ridge regression (KRR) to retrieve atmospheric temperature and humidity profiles from IASI satellite data. The researchers developed a nonlinear machine learning approach using KRR to improve upon the current linear regression method. They found that KRR outperformed linear regression, providing very good results over both ocean and land areas. KRR was able to handle the nonlinear relationships in the data and the complex retrieval problem more accurately and efficiently than previous methods. The results demonstrated that KRR is a promising technique for atmospheric profile retrieval from IASI radiance measurements.

GENERATING FINE RESOLUTION LEAF AREA INDEX MAPS FOR BOREAL FORESTS OF FINLAND...
This document summarizes research generating fine-resolution leaf area index (LAI) maps for boreal forests in Finland using satellite imagery. Two methods were used: 1) an empirical model based on the reduced simple ratio vegetation index and 2) inversion of a forest reflectance model. Field measurements of LAI from over 1000 plots were used to develop and validate the models. The empirical model using scene-specific parameters produced LAI maps for 2000 and 2006 with realistic patterns, though some overestimation. Comparison to MODIS LAI showed generally good agreement but some systematic differences likely due to phenological and calibration issues. The empirical method was selected for producing the LAI maps.
IGARSS 2011.ppt
This document presents a new approach for classifying multispectral remote sensing images using weighted pixel statistics.

Future work is outlined to further evaluate performance.
FR3.TO5.2.pptx
This document presents a method for estimating net surface radiative fluxes over rugged terrain using satellite measurements. Artificial neural network models are developed to retrieve net shortwave and longwave fluxes over horizontal surfaces. Topographic radiation models are then used to correct for the effects of terrain, accounting for factors like shading and sky view ratio. The method is validated using in situ radiation data and applied to a case study area in Tibet, showing that considering topography results in wider variation of estimated fluxes compared to assuming a horizontal surface. Accounting for topographic effects is found to be important for accurately representing surface radiation budgets over mountainous regions.

The document evaluates SMAP soil moisture algorithms using SMOS data. SMOS data was reprocessed to simulate SMAP observations at 40 degrees incidence angle. The Single Channel Algorithm was implemented using this SMOS/SMAP data set with different ancillary datasets. Initial results show the SCA using MODIS data performs well compared to in situ observations. Using vegetation polarization also performs satisfactorily, though vegetation parameters may need to be specific to land cover types to reduce bias in different areas. Overall results indicate SMAP algorithms can meet the target 0.04 m3/m3 accuracy requirement with further analysis and research. This evaluation will help select and develop the SMAP passive level 2 soil moisture algorithm.
RoughSurfaceModels.ppt
The document summarizes recent advances in analytical models for electromagnetic scattering from rough surfaces, including the statistical integral equation method (SIEM) and the extended advanced integral equation method (E-AIEM). SIEM incorporates surface slope statistics into the Kirchhoff approximation to improve accuracy. E-AIEM makes fewer assumptions than previous models and includes correction terms involving the error function for more accurate cross and complementary scattering coefficients, especially when surfaces or media are lossy. Testing shows these new methods agree well with full-wave simulations and experimental data.
Migliaccio.pdf
This document presents research on using dual-polarized COSMO-SkyMed SAR data to observe metallic targets at sea. It discusses how ship detection is important for maritime surveillance. Traditional tools like visual observation are now supplemented by remote sensing technologies like SAR.

A highly magnetized twin-jet base pinpoints a supermassive black hole
Supermassive black holes (SMBH) are essential for the production of jets in radio-loud active galactic nuclei (AGN). Theoretical
models based on (Blandford & Znajek 1977, MNRAS, 179, 433) extract the rotational energy from a Kerr black hole, which could
be the case for NGC1052, to launch these jets. This requires magnetic fields on the order of 103 G to 104 G. We imaged the vicinity
of the SMBH of the AGN NGC1052 with the Global Millimetre VLBI Array and found a bright and compact central feature that is
smaller than 1.9 light days (100 Schwarzschild radii) in radius. Interpreting this as a blend of the unresolved jet bases, we derive the
magnetic field at 1 Schwarzschild radius to lie between 200 G and 8:3 104 G consistent with Blandford & Znajek models.

This document describes measurements taken of the infrared signature properties of a micro gas turbine engine exhaust plume. An infrared camera and spectroradiometer were used to measure the wideband emission and spectral emission properties of the plume at different engine rotational speeds, aspect angles between the camera's field of view and the plume, and at different positions along the plume. The goal was to characterize the plume's infrared radiometric properties to allow for numerical modeling of gas turbine plumes in infrared simulation software. The measurements provide data on how plume intensity varies with engine speed and aspect angle, as well as the spectral radiance content of the plume at different positions, which can be used to construct models of micro and larger-

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
