Science

The science of terrestrial geophysics involves measuring particles, fields, and radiation associated with both the solid (internal) Earth, its surface (including the hydrosphere [oceans]), and the external environment (mainly fields surrounding Earth and extending outward hundreds to thousands of kilometers.

NPOESS is primarily focused on providing high quality data products to its user community. Earth-sensing satellites, with diverse sensors mounted on sophisticated platforms, are in Earth orbit or soon to be launched. These sensors are designed to cover a wide range of the electromagnetic spectrum and generate enormous amounts of data that must be processed, stored, and made available to program users.
