Science Themes

MRV & Decision Support

Greenhouse gas emission inventories, forest carbon sequestration programs (e.g., Reducing Emissions from Deforestation and forest Degradation (REDD and REDD+), cap-and-trade systems, self-reporting programs, and their associated monitoring, reporting and verification (MRV) frameworks depend upon data that are accurate, systematic, practical, and transparent. A sustained, observationally-driven carbon monitoring system using remote sensing data has the potential to significantly improve the relevant carbon cycle information base for the U.S. and world. Work is needed to prototype and mature relevant measurement and analytical approaches for use in support of MRV frameworks. NASA's Carbon Monitoring System (CMS) project is prototyping and conducting pilot studies to evaluate technological approaches and methodologies to meet this need. CMS products also include a set of analyses and assessments, analytical methods, communication and visualizations tools that provide timely and useful information to decision-makers.

Ocean Biomass

Ocean Biomass refers to the total mass of all living matter living in the oceans. Oceans also play an important role in the carbon cycle, as the surface and deep ocean waters hold a combined 38,000 gigatons of carbon. CMS scientists are focusing their efforts in researching concentrations of phytoplankton and distribution of calcifiers in the oceans (and to a lesser extent in the Great Lakes), which play an important role in controlling how much carbon is exchanged between the oceans and the atmosphere.

Land-Ocean Flux

Land-Ocean Flux refers to the exchange of carbon between the land and coastal waters. In order to understand the dynamics that control the movement of carbon from land to the ocean, CMS scientists are using land-based and ocean-based models together to model terrestrial watershed processes in combination with coastal oceanic processes.

Land-Biomass

Land Biomass is the total mass of all living matter on land, including all above ground grasses, trees, and shrubs. When biomass is removed through deforestation or burning, the carbon stored in the plants is released into the atmosphere. CMS scientists are improving current methods for measuring how much land biomass exists and its role in the carbon cycle.

Ocean-Atmosphere Flux

The exchange of carbon between the air and ocean is known as Ocean-Atmosphere Flux. Current estimates indicate that the amount of carbon the ocean is able to uptake is decreasing, causing the atmospheric concentrations of carbon to increase. CMS projects funded under this activity seek to better estimate the exchange of carbon between the ocean and the air.

Global Surface-Atmosphere Flux

Global Surface-Atmosphere Flux refers to the total amount of carbon being moved annually between the land and ocean surface and the atmosphere.

Land-Atmosphere Flux

The exchange of carbon between the land and the air is referred to as Land-Atmosphere Flux. CMS scientists are collecting better estimates of land biomass to use in models which predict how much carbon is released through biomass burning and deforestation.
