CATT (Combined Aerosol Trajectory Tool) is a community tool for analyzing the transport of air pollutants using back trajectories. It consists of three components: the Trajectory Aggregator Tool which extracts and aggregates trajectory data, the Chemical Filter Tool which filters trajectories by chemical data, and the Trajectory Browser Tool which allows browsing trajectories for specific sites. CATT is currently functional and being tested, with plans to continue adding new trajectory and air quality data and expanding functionality.

CAMS GA Validation by Eskes
This document summarizes validation activities from the Copernicus Atmosphere Monitoring Service (CAMS). CAMS provides regular validation reports on its global real-time analysis-forecast service, global reanalysis, and regional models. Validation products include comparisons to satellite data, ground-based observations, and independent analyses. Recent results show improvements matching aerosol and NO2 satellite data as well as capturing dust events and ozone depletion episodes. CAMS validation involves acknowledgements to over 30 groups providing measurements for evaluation.

TGS Arcis- East Coast- Southeast Grand Banks
The document summarizes seismic acquisition and processing parameters for a marine seismic survey conducted off the coast of Newfoundland, Canada between July and October 2015. The survey covered 14,599 km using a 24-bit streamer towed behind the vessel Atlantic Explorer. Initial processing was done by PGS and included noise attenuation, wavefield separation, and extrapolation. Further processing will be done by Arcis to produce outputs such as pre-stack migrated gathers, raw and processed migrations, velocities, and angle stacks.
Oil and Gas Imaging, pumpsandpipesmdhc
Seismic imaging is used in oil and gas exploration to determine reservoir geometry and properties by analyzing acoustic echo reflections from subsurface layers. It is a two-step process that first uses varying source-receiver separations and tomography to determine subsurface velocities, and then backpropagates measured sound waves to form images. Advancements include more accurate imaging algorithms, improved velocity modeling tools, and increased data acquisition apertures, but challenges remain such as illumination limitations, complex velocity models, imaging steep dips and structures, and issues of resolution and noise.

This document discusses improving atmospheric measurements on Ships of Opportunity (SOOP) as part of the Ringo Task 3.2 project. Three SOOP lines - SOOP Tavastland, SOOP Colibri, and SOOP Atlantic Sail - are being equipped with instrumentation to measure atmospheric CO2, CH4, and other greenhouse gases to standards matching the ICOS Atmospheric Thematic Centre. Initial results from SOOP Colibri show data quality matching these standards and capturing gradients and variability not seen in models. Next steps include finalizing the setup on SOOP Tavastland and assessing the added value of these new SOOP measurements for inverse modeling.2005-01-18 Combined Aerosol Trajectory Tool, CATT Illustrated Instruction Manual

The document reports on an evaluation of the Automated Surface Observing System (ASOS) light scattering network. It analyzes data from 220 ASOS stations to evaluate the precision and performance of the ASOS visibility sensors. It finds that some stations show excellent correlation between duplicate sensors while others show poorer correlation or significant offsets. It also examines diurnal patterns and the effects of relative humidity on visibility readings.
Undergrad Senior Design Thesis
This document presents a simulation study and analysis of an improved navigation solution for GPS. It discusses the key parameters used in GPS like ephemeris, clock, and almanac data. It then describes the GPS signal structure and data frames. It proposes using a software-defined receiver approach and implementing tracking loops and position determination using a Kalman filter. It shows how the Kalman filter can optimally track carrier phase and code measurements to estimate position and overcome limitations of traditional tracking loops. Simulation results demonstrate the Kalman filter's ability to accurately estimate position and velocity. The document concludes that the Kalman filter is well-suited for GPS navigation due to its recursive nature and ability to optimally process noisy measurements.

2005-01-28 Assessment of the Speciated PM Network (Initial Draft, November 2004)
This document summarizes the assessment of the speciated particulate matter (PM) monitoring network in the United States. It finds that since 2000, speciated PM monitoring has expanded from 50 sites to over 350 sites. By 2003, the spatial coverage of speciated monitoring was high across the US. For long-term sulfate averages, estimation errors were below 1 microgram per cubic meter in the East. The 350 monitoring sites provide at least 10 times more spatial characterization of PM than the daily sampling frequency alone. The document recommends establishing continuous and automated network assessment as a routine part of ongoing PM monitoring.
Methane Maps of DISH and Flower Mound (Texas) - Likely Indication of Benzene ...
Methane mapping uses a fast, accurate, and easy-to-use methane measurement tool mounted in a vehicle to generate maps showing methane concentrations across an area. The tool measures methane at parts-per-billion resolution in seconds. Maps can help identify potential natural gas leaks and distinguish between natural and human-caused methane sources to target areas for further study. One example map showed a methane "ribbon" along the vehicle's path and a peak indicating a likely roadside source located using wind direction data.

This document discusses the challenges of characterizing air pollution using remote sensing observations over China. It describes the seven dimensions of data - spatial, height, time, particle size, composition, shape, and mixing - needed to fully characterize air pollution. While each individual observation method or data set has limitations, together they can provide consistent global-scale observations. There remain significant challenges to integrating data from multiple sensors to accurately measure air pollution. International collaboration combining global satellite data with detailed local observations in China may help advance progress in addressing this issue.
2013-04-30 EE DSS Approach and Demo
The document describes the Exceptional Event Decision Support System (EE DSS), a tool to help states and EPA regions implement the EPA's Exceptional Events Rule.

121117 eedss briefing_nasa_epa
This document summarizes the Exceptional Event Decision Support System (EE DSS) which uses NASA satellite data and the Navy Aerosol Analysis and Prediction System (NAAPS) model to help with air quality management decisions regarding exceptional events like smoke and dust events. The EE DSS has been developed since 2005 with NASA support and is now ready to serve air quality management at the federal, regional, and state levels. It can automatically detect and analyze events, display relevant data through interactive maps and cross-sections, and its tools have helped explain declines in exceptional event flags and PM2.5 concentrations from 2006-2012. Coordination is proposed with NASA and EPA for continued application of the EE DSS to smoke and dust events in
120910 nasa satellite_outline
This document discusses the usefulness of satellite observations for air quality applications and regulatory requirements. It outlines six key air quality requirements that satellites can help address, such as determining compliance with air quality standards and identifying long-range pollution transport events. The document also notes how satellites can help improve emissions estimates, characterize long-range transport of pollution, and increase interaction between air quality and remote sensing scientists. However, it cautions that relating satellite aerosol optical depth measurements directly to ground-level PM concentrations currently has too much uncertainty for regulatory or public health applications.
120612 geia closure_ofeo_ms_soa_subm
The document discusses tools for closing the gap between emissions, observations, and models of air quality. It proposes a service oriented architecture and network to integrate multiple datasets from observations, emissions, and models. This would allow iterative evaluation and improvement of models by comparing them to observations and adjusting emissions estimates to reduce biases. The end goal is to provide the best available composition of the atmosphere by integrating the best observations, emissions estimates, and models.
110414 extreme dustsmokesulfate
This proposal outlines a study on the influence of weather and climate events on air quality issues like dust, smoke, and sulfate events.
