EPA Remote Sensing Information Gateway (RSIG); A Channel to Facilitate use of TEMPO data for Decision Support 1St TEMPO Applications Workshop Shelby Center University of Alabama, Huntsville Huntsville, AL July 12-13, 2016 Jim Szykman National Exposure Research Laboratory Office of Research and Development USEPA

RSIG Background The Remote Sensing Information Gateway (RSIG) grew out of applied research efforts to explore using distributed data access methods for greater access to large volume data sets, including NASA and NOAA satellite data and EPA modeled data sets. Over the past several years RSIG has focused efforts on extending access and increasing the use of several satellite (aerosol) and aircraft datasets to support EPA applied research. The system provides on-demand access to a variety relevant air quality/atmospheric composition data sets, with functionally to subset data in time and space, re-grid onto model grids, and visualize multiple data sets in the same space (including 3-D). Others involved along the way include: U.S. EPA (ORD & OAQPS) Modeling Groups, NASA MODIS, VIIRS and CALIPSO Aerosol Science Teams, NOAA-NESDIS (GOES and VIIRS Aerosol Product(s)), MOZAIC/IAGOS PI’s, NASA Airborne Data for Assessing Models (ADAM) Developers, and Several NASA AQAST members. Satellite, aircraft, and in-situ data sets are collected at differing temporal and spatial scales. Multiple file formats makes it resource intensive to download, process, and put data onto same time and space scale for individual user. RISG is a web-based used which integrates various measurement data together into the same space and time with model where feasible.

Applet vs. Application - RSIG Front End RSIG2D applet (web-based) RSIG3D application (standalone) The Remote Sensing Information Gateway (RSIG) is a web-based distributed data system to visualize and access large volume data sets, including NASA and NOAA satellite data and EPA modeled data sets, focused on air quality applied research. The result is a system capable of providing on-demand access to a variety relevant air quality/atmospheric composition data sets, with functionally to subset in time and space and re-grid on model relevant grids (including 3-D).

USGEO Satellite Needs Working Group (SNWG): Identifying Priority Federal Satellite User Needs Charter signed April, 2016 The SNWG supports a process by which Federal departments and agencies can communicate their Earth observation satellite measurement or product needs to NASA and other providers of satellite observations. Information gathered during this process will be used to influence decisions on future sensors placed into orbit. Transparent process: Agency needs will be tracked and attributed with information on which are planned be met or remain unmet. It is the intent of USGEO to release a list of satellite needs to the public.

Some Thoughts Unlike other NASA missions, TEMPO is a very applied mission; Rapidly demonstrating applications at an ARL7+ will influence the perceived value of the mission. RSIG is one of several existing systems that provides an existing outlet and user base for TEMPO data. Need to identify similar user systems/applications as outlets for TEMPO data, e.g. WRAP- Web System, NOAA/NESDIS-IDEA, EPA-AIRNow, etc., and take advantage of existing channels and the many hours of human capital and resources expended on these systems. Can multiple user systems work together to develop a reusable TEMPO web-service/api? Traditional AQM analysis activities are retrospective, typically 2-3 years for current year. Can we explore the use TEMPO for dynamic AQM?
