ROSES-2020 Program Element A.5 Carbon Cycle Science solicits proposals for research focused on carbon stocks and fluxes between and within freshwater, marine systems, and land ecosystems, and their exchange with the atmosphere. It also targets improving understanding of carbon cycle processes and feedbacks in critical ecosystems that are particularly vulnerable to environmental change. Substantive use of remote sensing and/or airborne data is required in all studies.


The research topics of interest for this program element are divided into two sub-elements, which are further divided into five research topics:


3.1: Carbon Fluxes between and within Land, Freshwater, and Marine Systems

3.1.1.    The Land-Ocean Continuum

3.1.2.    Carbon Cycle of Critical Ecosystems: Vulnerability of Tropical Forests

3.1.3.    Fluxes and Biogeochemistry of Carbon within Oceans

3.2: Carbon Fluxes between Ecosystems and the Atmosphere

3.2.1.    Carbon Fluxes between Terrestrial Ecosystems and the Atmosphere

3.2.2.    Carbon Fluxes between Oceans and the Atmosphere


ROSES-2020 Amendment 49 releases final text for A.5 Carbon Cycle Science. Notices of intent are requested by September 28, 2020 and the due date for proposals is December 3, 2020.


On or about August 26, 2020, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2020” (NNH20ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA’s ROSES blog at:
