MODIS/Terra Aerosol 5-Min L2 Swath 3km - NRT

The only differences between the existing 10km algorithm and the new 3km algorithm are: 1) the size of the pixel-arrays defining each retrieval box ( 6x6 retrieval boxes of 36 pixels at 0.5km resolution for 3km algorithm as oppose to 20x20 retrieval boxes of 400 pixels at 0.5km resolution for 10km product); 2) the minimum percentage of good” pixels required for a retrieval (a minimum of 5 pixels over ocean and 6 pixels over land instead of a minimum of 10 pixels over ocean or 12 pixels over land for 10km product retrieval); 3) the 10km algorithm attemptes a poor quality retrieval while 3km algorithm does not.

Everything else is same in two products. For more information on C6.1 changes and updates, visit the MODIS Atmosphere website at: modis-atmosphere.gsfc.nasa.gov/documentation/collection-61
