Description

The MODIS/Terra Aerosol Optical Thickness Daily L3 Global 0.05Deg CMA Neal Real Time (NRT) Product (MOD09CMA) is a daily level 3 and global product. It is in linear latitude and longitude (Plate Carre) projection with a 0.05Deg spatial resolution. This product is derived from MOD09IDN, MOD09IDT and MOD09IDS for each orbit by compositing the data on the basis of minimum band 3 (459 - 479 nm band) values (after excluding pixels flagged for clouds and high solar zenith angles).
