Carbon Cycle Science (ROSES 2020)

This announcement offers opportunities for Carbon Cycle Science investigations within the NASA Earth Science Division Research and Analysis Program. NASA seeks proposals that make significant use of remote sensing data to improve understanding of changes in the distribution and cycling of carbon among the active land, ocean, coastal, and atmospheric reservoirs, and how that understanding can be used to establish a scientific foundation for societal responses to environmental change.

The overall goals for NASA's Earth Science program are documented in the NASA Science Mission Directorate 2020-2024 Science Plan and NASA 2018 Strategic Plan. NASA Earth Science research focuses on using space-based observations to safeguard and improve life on Earth, often supplemented with other types of observations (e.g., aircraft and/or surface measurements) and then combined and synthesized in models. Carbon Cycle Science research is supported by many research and applied science programs at NASA, including, but not limited to, NASA’s Carbon Cycle and Ecosystem (CCE) Focus Area and the individual research and analysis programs that support it; significant investments are also made by many of the CCE-related satellite programs, which have separate competed science teams for data exploitation.

The NASA Earth Science Program goals for Carbon Cycle Science are to improve understanding of the global carbon cycle and to quantify changes in atmospheric CO2 and CH4 concentrations, as well as terrestrial and aquatic carbon fluxes and storage in response to fossil fuel combustion, land use and land cover change, and other human activities and natural events. NASA carbon cycle research encompasses multiple temporal and spatial scales and addresses atmospheric, terrestrial, and aquatic carbon stocks and fluxes, their coupling within the global carbon cycle, and interactions with climate and other aspects of the Earth system. Observations from space provide a platform for NASA carbon cycle research; they contribute toward the goals of major U.S. Global Change Research Program (USGCRP) activities, including the Carbon Cycle Science program’s U.S. North American Carbon Program (NACP) and the Ocean Carbon and Biogeochemistry (OCB) program. NASA carbon cycle research also contributes toward the goals of the Ocean Policy Committee and the related activities of its member federal agencies.
