Search by geophysical quantities
Corresponding products are searchable from various geophysical quantities (precipitation, snow depth, vegetation, ocean color, etc.) classified by atmosphere, cryosphere, terrestrial, and ocean groups.
Physical quantities are shown in the following list. They may be changed corresponding to the spacecraft operation.
