Deep Space Earth Observations
Session ID#: 156917
Session Description:
Earth sensors of the Deep Space Climate Observatory (DSCOVR) measure radiative fluxes of the entire sunlit Earth. EPIC measures key spectral characteristics at 10 km resolution, while NISTAR measures the whole Earth reflected and emitted energy in four broadband channels. The unique near backscatter angle of DSCOVR is used to measure ozone, sulfur dioxide, aerosols, clouds, oceans, vegetation, and to estimate UV radiation at the Earth’s surface. The session focuses on the novel perspective of DSCOVR products obtained from L1 and how DSCOVR measurements complement existing data from low Earth orbit and geostationary satellites. Particular attention will be paid to observations of aerosols and sulfur dioxide transport, ocean surface radiation, vegetation properties, solar glints and diurnal distribution of clouds, including their role in Earth’s radiation budget. Applications of DSCOVR data to study exoplanets will be also considered.
