MODOCGA.006 Terra Ocean Reflectance Daily Global 1km
Description
The MODOCGA V6 ocean reflectance product consists of
1 kilometer reflectance data from Terra MODIS bands 8-16. The product
is referred to as ocean reflectance, because bands 8-16 are used
primarily to produce ocean products, but this is not an ocean product
as the tiles produced are land tiles.
