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.
has been providing to its users GOES
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 -
