Earth Polychromatic Imaging Camera (EPIC)


The Earth Polychromatic Imaging Camera (EPIC) is a 10-channel spectroradiometer (317 – 780 nm) aboard NOAA’s Deep Space Climate Observatory (DSCOVR) spacecraft (which is a partnership between NOAA, NASA, and the U.S. Air Force). EPIC provides color images of the entire sunlit face of Earth at least once every two hours from 1 million miles away. This point is called the Earth-Sun Lagrange-1 (L-1) point, and is where the gravitational pull of Earth and the Sun are equivalent and hold the observatory in place. DSCOVR’s location gives it a unique angular perspective that is used to measure ozone, aerosols, cloud reflectivity, cloud height, vegetation properties, and UV radiation estimates at Earth's surface.
