Deep Space Climate Observatory (DSCOVR)

DSCOVR, formerly called Triana, is the first Earth-observing satellite in an Lagrange-1 or L1 orbit. It supports a number of scientific instruments, including EPIC and NISTAR. EPIC (Earth Polychromatic Imaging Camera) is a 10-channel sepctroradiometer that provides daily 13 (in winter) or 22 (in summer) 10 narrow band spectral images of the entire sunlit face of Earth.
