IDEA-International Air Quality
Trajectory forecast of aerosols (where aerosol optical depth is larger than 0.4)
over the next 48 hours based on the real-time Terra/MODIS MOD04 aerosol products.

IDEA-I: Infusing satellite Data into Environmental Applications - International (2012)
Model developers: James Davies (SSEC), Brad Pierce (NOAA/STAR/ASPB),
Eva Schiffer (SSEC), Kathy Strabala (SSEC)

IDEA-I software package identifies high aerosol content (high aerosol optical depth) based on the real-time Terra and Aqua (at present only Terra MODIS data is proccessed) MODIS MOD04 aerosol optical depth products. Then a trajectory model is run in every day for the next 48 hours starting at 00 UTC using 1 hour time steps. The result predicts the horizontal and vertical movement of the aerosols. Beyond the MOD04 data the necessary ancillary dataare the outputs of the Global Forecast System (GFS) model (with the resolution of 0.5°x0.5°).
