The Remote Sensing Information Gateway (RSIG) is a tool for selecting, downloading, assembling, and visualizing atmospheric data. After the data has been assembled, it can be stored on the user’s workstation, if desired. RSIG is developed by the US Environmental Protection Agency (EPA).

The RSIG application is operated by selecting from among fifteen or so variables available from two Moderate Resolution Imaging Spectroradiometer (MODIS) satellites, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, the EPA’s CMAQ modeling runs, and Airnow/Air Quality System (AQS) ozone and particulate-matter observations. The application then assembles the data from local files or by submitting requests over the Internet to data repositories at NASA, NOAA, etc. RSIG then presents a visualization of the data on a latitude-longitude map, automatically locating the data in correct geographic position. RSIG system includes program code that runs at NASA and NOAA to select and subset large datasets at the source computer center. Transmission over the Internet to the EPA is thereby accelerated compared to conventional techniques. RSIG can save the collected data in binary External Data Representation (XDR) format, NetCDF format, or as an ASCII spreadsheet; and it can save the visualized images as MPEG or PNG format files.

Acess and Status

The RSIG documentation server is on the EPA Intranet at http://linden.nesc.epa.gov/rsig. The RSIG application is operable but is still in the final stages of development. As of May, 2007, the application can be accessed at http://rtpmeta.epa.gov/portal/rsig2D.html. All workstation users connected to the EPA network can access these servers. Those outside of the EPA network do not have access.

Sponsorship and Contacts

The RSIG application has been sponsored and managed by ORD’s National Exposure Research Lab (NERL). Dr. Fred Dimmick, Chief of the Process Modeling Research Branch, is the responsible EPA manager. It is being developed by the EPA Environmental Modeling and Visualization Laboratory.
