MODIS/Aqua Near Real Time (NRT) Aerosol Optical Thickness Daily L3 Global 0.05-Deg CMA

The MODIS Aerosol Optical Thickness (MYD09CMA) is a daily level 3 global product. It is in linear latitude and longitude (Plate Carre) projection with a 0.05Deg spatial resolution. This product is derived from MYD09IDN, MYD09IDT and MYD09IDS 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).
