The Ocean Biology Processing Group (OBPG) produces and distributes a standard suite of ocean color products for all compatible sensors at Level-2 and Level-3, plus sea surface temperature (SST) products from MODIS and VIIRS. The OBPG also produces a suite of Level-3 evaluation products. The descriptions and references for these standard and evaluation products (provided below) are intended to satisfy the Algorithm Theoretical Basis Document (ATBD) requirement as defined by the NASA Earth Observing System Project Science Office.
Standard Ocean Color Products
The concentration of the photosynthetic pigment chlorophyll a.
The diffuse attenuation coefficient for downwelling irradiance over the first optical attenuation layer.
The spectral marine absorption and backscattering coefficients of water column constituents.
The concentration of particulate organic carbon.
The concentration of particulate inorganic carbon.
Daily mean photosynthetically available radiation (PAR) at the ocean surface.
PAR the ocean surface at the time of the satellite observation. (MODIS only)
Relative measure of water-leaving radiance associated with chlorophyll fluorescence. (MODIS only)
The at-surface spectral remote-sensing reflectances observed by the satellite instrument after atmospheric correction. The aerosol optical thickness and Ångström data products are also described.
Standard Sea Surface Temperature Products
Sea surface temperature derived from long-wave (11-12 µm) thermal radiation. (MODIS & VIIRS)
Sea surface temperature derived from short-wave (3-4 µm) thermal radiation. (MODIS only)
