Earth Polychromatic Imaging Camera (EPIC)
Ten-channel UV/VIS/NIR spectroradiometer on DSCOVR imaging the entire sunlit Earth disk from L1.
EPIC is the Earth-observation sensor on DSCOVR at Sun-Earth L1, configured as a ten-channel UV/VIS/NIR spectroradiometer and full-disk Earth camera.[1] It images the sunlit Earth disk in ten narrow-band spectral channels spanning 317.5-779.5 nm.[1] The optical system uses a 2048 x 2048 pixel CCD with a 30-cm aperture Cassegrain telescope.[1] Its imaging cadence covers the entire sunlit Earth every 60 to 100 minutes, with about 8 x 8 km native projected pixel size near the equator and about 24 x 24 km downlinked images after onboard averaging.[1][2] Its Earth-observation applications include ozone and SO2, aerosols, cloud reflectivity and cloud height, vegetation properties, and UV-radiation estimates at the Earth's surface.[1]

- Vegetation index mappingvia DSCOVR
EPIC visible/NIR channels support vegetation products from the full-disk L1 view.
- Tropospheric column mapping (NO2/SO2)via DSCOVR
EPIC UV channels support SO2 and ozone/aerosol products; no ozone-specific method exists.
