English: The Deep Space Climate Observatory (DSCOVR) Project addresses the National Oceanic and Atmospheric Administration's (NOAA) space weather environmental monitoring objectives by providing measurements of the solar wind magnetic field, and the solar wind plasma ion temperature, velocity and density. NOAA has transferred funds to NASA for the refurbishment of DSCOVR and its solar wind sensors, with NASA acting as the refurbishment/acquisition agent on behalf of NOAA. DSCOVR also includes the NASA Science Mission Directorate funded Earth Science instruments that provide high-resolution whole earth multispectral imagery and earth radiometry data, and the Heliophysics Science sensor that provides measurements of the solar wind electron distribution.
