Each level 3 SMI file is approximately 8 MB in size. The level 3 browse files consist of a subsampled version of the SMI chlorophyll a concentration product. Meteorological and ozone climatology data files are also suitable for SeaWiFS data processing and can be used to interpolate missing values in the NRT data files. Climatology data files can be obtained separately by FTP from the DAAC SeaWiFS data browser. The actual ancillary data parameters used in processing are meridional wind, zonal wind, surface pressure, relative humidity, and total ozone.
All products are available as gridded global data.
