Abstract:
Comparing Suomi-NPP VIIRS aerosol retrievals to AERONET ground measurements plays a vital role in evaluating the maturity status of the VIIRS aerosol products. The study applied the Multi-sensor Aerosol Product Sampling System (MAPSS) to compare VIIRS aerosol products and the heritage MODIS (C5.1 & C6) and MISR aerosol products with AERONET measurements over the VIIRS's operational period. The accuracy and precision of the VIIRS aerosol products, as determined by comparison with AERONET measurements, were evaluated against JPSS-1 performance evaluation threshold values. Regional, seasonal and geometrical dependence of the deviation of the satellite retrievals from the ground measurements were characterized and compared. Results indicate comparable performance of the VIIRS aerosol optical depth EDR and Ångström Exponent EDR (over ocean) to their counterparts from the heritage sensors. The findings on the spatial and temporal patterns of the differences between the satellite aerosol retrievals and AERONET will aid in the improvement of the VIIRS aerosol products as we transition from NPP to the JPSS-1.
