NASA's ASDC has released the Deep Space Climate Observatory (DSCOVR) Earth Polychromatic Imaging Camera (EPIC) Level 1A data products, and offering a rare and scientifically valuable perspective of the Moon as observed from Lagrange point L1.
The EPIC L1A Lunar Version 1 dataset provides calibrated radiance measurements of the Moon appearing alongside the Earth when the Earth is not in the field of view from approximately one million miles away. The EPIC Level 1A Miscellaneous dataset provides calibrated, 10-channel spectroradiometric imagery of the Moon transiting across the Earth's disk, dark space or Jupiter. The images of the Moon transiting across the Earth's disk or appearing alongside Earth included in the miscellaneous dataset provide a distinctive perspective of the Earth-Moon system from approximately one million miles away, offering valuable information for Earth-Moon system dynamics.
Mission/Campaign/Project Background
DSCOVR is a NOAA/NASA joint mission positioned at the Sun-Earth Lagrange point L1, designed to monitor solar wind conditions and capture continuous imagery of the sunlit face of Earth. EPIC aboard DSCOVR is a 10-channel spectroradiometer (317–780 nm). The mission's primary objective is to provide real-time solar wind data for space weather forecasting while simultaneously enabling unique Earth observation science through the EPIC instrument.
EPIC's vantage point at L1 offers a singular perspective of the Earth-Moon system not achievable from low Earth orbit or ground-based platforms, making occasional lunar observations — including views of the fully illuminated far side of the Moon invisible from Earth — an extraordinary scientific opportunity.
