NASA’s Earth science research aims to utilize global measurements to better understand the Earth system and interactions among its components, with the ultimate goal of predicting Earth system behavior. Fulfillment of this goal requires both shorterterm process-oriented measurements and longer-term satellite measurements of a limited number of environmental properties. For the latter, a key requirement is the provision of well-calibrated, multiyear measured radiances.

The Deep Space Climate Observatory (DSCOVR) mission is a multiagency (National Oceanic and Atmospheric Administration [NOAA], U.S. Air Force, and NASA) mission launched on 11 February 2015 with the primary goal of making unique space weather measurements from the first Sun-Earth Lagrange point (L1). The L1 point is on the direct line between Earth and the Sun located 1.5 million km from Earth. The spacecraft is orbiting this point in a six-month Lissajous orbit with a spacecraft-Earth-Sun angle varying between 4 and 12 degrees. While the primary science objective of the DSCOVR mission is to provide solar wind thermal plasma and magnetic field measurements to enable space weather forecasting by NOAA, the secondary goal is to provide measurements of the Earth system.

Proposals are sought for analyses using existing algorithms to deliver EPIC Level-2 or higher science products—possibly with related algorithm maintenance and calibration activities. Proposals for enhanced or new Level-2 or higher product algorithm development (see below) will also be considered. These proposals must be scientifically compelling and clearly describe how the proposed solutions differ from existing algorithms and products. Such proposals must also describe the potential and/or any planned utilization of the new and/or improved algorithms to address scientific questions.

NASA is also seeking proposals that use NISTAR Level-1 products to determine the Earth reflected and radiated irradiance with an accuracy of 1.5% or better, yielding the production of Level 2 shortwave and longwave flux products. Proposals to improve the NISTAR calibrations based on in-flight data will also be considered.
