MODIS Collection 5 Deep Blue Aerosol Product
 |
 |
The MODIS Aerosol Product monitors the ambient aerosol optical thickness over the oceans globally and over a portion of the continents. The additional Deep Blue product fills in some of the missing continental areas in Collection 5.1. Further, the aerosol size distribution is derived over the oceans. Daily Level 2 data are produced at the spatial resolution of a 10x10 km2 (at nadir)-pixel array. There are two MODIS Aerosol data product files: MOD04_L2, containing data collected from the Terra platform; and MYD04_L2, containing data collected from the Aqua platform.
