The NASA-Research Opportunities in Science of Earth and Space (ROSES) Carbon Cycle Science Solicitation, produced in collaboration with members of USGCRP's Carbon Cycle Interagency Working Group (CCIWG) was released on 2/14/203. Proposals to improve the understanding of changes in the distribution and cycling of carbon among the active land, ocean, and atmospheric reservoirs and how that understanding can be used to establish a scientific foundation for societal responses to global environmental change are being sought in alignment with the research agenda of the U.S. Global Change Research Program (USGCRP), and, specifically, its U.S. Carbon Cycle Science Program, as well as the goals and objectives of the individual CCIWG agencies participating in this joint solicitation which can be accessed via this link.
