Deep Space Earth Observations
Session ID#: 75258
Session Description:
The Deep Space Climate Observatory (DSCOVR) is located near the Earthâs L1 point where it monitors the solar wind and observes the Earth with two sensors. Earth sensors measure radiative fluxes of the entire sunlit Earth and key spectral characteristics at 10-15 km resolution. The unique near backscatter angular perspective of DSCOVR is used to measure ozone, sulfur dioxide, aerosols, clouds, vegetation, and to obtain UV radiation estimates. The first Earth science DSCOVR products were released in 2018. The session focuses on the novel perspective of DSCOVR products obtained from L1 and how DSCOVR measurements complement existing data from low Earth and geostationary orbits. Particular attention will be paid to observations of aerosols and sulfur dioxide transport, photosynthesizing systems and diurnal distribution of clouds, including their role in Earthâs radiation budget. New uses, such as application of DSCOVR data to study ocean color and exoplanet simulation studies, will be considered.
