4. Conclusions
NCEP recently initializes the efforts to develop global aerosol forecasting and
assimilation capabilities via NOAA/NCEP-NASA/GSFC-Howard University collabor-
ations. Two impact studies are presented in this paper. First, dust simulations from
off-line GFS-GOCART system are used as lateral aerosol BCs for NCEP AQF (an
experimental configuration). The incorporation of dynamic LBCs significantly
improved the PM forecasts for the 2006 summer episode. Second, results of
GDAS experiments for the 2006 summer period are presented. Change in model
forecasts arises from the direct radiative effects. The verification against analysis
and observations indicates a neutral-to-positive impact due to improved treatment
of aerosols.
