Air Quality Remote Sensing Program
GOES Aerosol Optical Depth

Satellite measured aerosol optical depth (AOD) has been shown to be a good proxy for pollution monitoring especially when long-range transport is involved. NESDIS / STAR has been providing to its users GOES AOD product in near real time since 2003. This product is available at 30-minute interval and 4 km X 4 km spatial resolution during the sunlit portion of the day. The EPA and NWS have been using the product for monitoring and forecasting applications.

and NWS experimental forecast during July 15 - August 15, 2004.
