Update on EPIC MAIAC V2 Algorithm: Atmospheric Correction

Alexei Lyapustin presented a new v2 MAIAC atmospheric correction algorithm for EPIC. The v2 algorithm introduced new projection removing spatial distortions, a more accurate retrieval of spectral surface reflectance using ancillary MAIAC MODIS BRDF dataset, and a new technique for simultaneous retrieval of aerosol optical depth and spectral absorption. AERONET validation shows that v2 significantly improved AOD accuracy compared to v1, while the retrieved single scattering albedo in the Blue shows a very good accuracy comparable to that of AERONET for both biomass burning smoke and mineral dust aerosols.
