The quantitative determination of global trends in the Earth’s atmosphere, ocean, cryosphere, biosphere, and land surface depends significantly on the ability of the scientific community to construct multiinstrument/multiplatform data sets based on satellite observations covering periods of a decade or longer. This effort, global in scope, also constitutes a global challenge, as most if not all such data sets will rely on satellite programs from multiple agencies and/or nations, in particular, requiring both the use of satellites primarily focused on research and the use of those intended for operations.

This ROSES program element (Satellite Calibration Interconsistency Studies) provides an opportunity for the research community to participate in the quantitative comparison of multiple satellite data products to facilitate the development of multiinstrument/multiplatform data sets involving satellites from multiple providers. Proposals responsive to this call must address interconsistency issues of two or more satellites, at least one of which must be one currently supported through NASA’s Earth Science Program, and at least one of which must be supported by some other organization (U.S. or foreign).

NOIs are now requested by October 14, 2015 and proposals are now due by December 8, 2015.
