SeaWiFS Deep Blue Aerosol Optical Depth and Angstrom Exponent Level 2 Data V004 (SWDB_L2) at GES DISC V004
The SeaWiFS Deep Blue (SWDB) Level 2 Product contains data corresponding to a single SeaWiFS swath using Deep Blue algorithm. There are about 15 Level 2 data files produced per day. Each contains retrieved aerosol properties averaged to a resolution of 3x3 SeaWiFS pixels (13.5x13.5 km at the center of the swath given 4.5km SeaWiFS pixels). The primary data parameters are aerosol optical thickness, and Angstrom exponent.

- Quality The SeaWiFS Deep Blue aerosol products have been validated by comparison with ground-based instruments from AERONET and MAN. The results are included in the following two papers: Sayer, et al (2012): Global and regional evaluation of over-land spectral aerosol optical depth retrievals from SeaWiFS, Atmos. Meas. Tech., 5, 1761-1778, doi:10.5194/amt-5-1761-2012 Sayer, et al (2012), SeaWiFS Ocean Aerosol Retrieval (SOAR): Algorithm, validation, and comparison with other data sets, J. Geophys. Res., 117, D03206, doi:10.1029/2011JD016599 For analyses over land, it is recommend using only data with a confidence flag value of 3. For analyses over oceans, data with confidence flag values of 2 or 3 may be used.
