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); see File:Rsig 10312007.pdf .
The RSIG application is operated by selecting from among fifteen or so variables available from the following data sources:
- Two Moderate Resolution Imaging Spectroradiometer (MODIS) satellites
- Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite
- EPA’s CMAQ modeling runs
- 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 uses program code that runs on NASA and NOAA servers 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 the following formats:
- Binary External Data Representation (XDR) format
- NetCDF format
- ASCII spreadsheet
- MPEG or PNG format files for visualized images
Access 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 (EMVL).
