Air Quality Forecast Verification Using GOES
AOD Quality Verification
NOAA /
NESDIS
has demonstrated the usefulness of 30-minute
GOES
AOD data
in verifying air quality forecasts. Using the developmental Community Multi-scale Air Quality (CMAQ) runs
made during the summer of 2004 and observations of GOES
AODs, NESDIS
scientists evaluated the AOD forecasts and reported the findings to
Journal of Applied Meteorology. The paper is currently in review. The National Centers for Environmental Prediction (NCEP)
will soon begin downloading GOES
AOD data for ingestion into its forecast
verification system.
The figure below shows comparison between GOES
AOD (top
left) and CMAQ AOD forecast (top right) valid for 17Z forecast on July 21,
2004. Bottom left plot shows the difference between the two and bottom
right plot shows frequency distribution of AOD for GOES
and CMAQ.
