Deep Space Climate Observatory (DSCOVR) Project

DSCOVR, formerly called Triana, is the first Earth-observing satellite in an Lagrange-1 or L1 orbit. It will be continuously viewing the planet with a 9-channel imager, the EPIC , and a single-pixel broadband radiometer, NISTAR . NASA Langley will be analyzing data from both instruments to determine cloud and radiation properties of the Earth-atmosphere system. This work is being directed by Co-Investigator Patrick Minnis, Atmospheric Sciences, NASA Langley Research Center(LaRC).
