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.
Figure shows mean bias between satellite measured aerosol
optical depth
and NWS experimental forecast during July 15 -
August 15, 2004.
