The Atmospheric System Research Program focuses on improved understanding of surface atmosphere exchanges of carbon, water, and energy, and their roles in ecosystem-climate interactions, as well as to quantify the convective transport of CO2, water, mass, and momentum. Researchers in this program –
- Observe the direct radiative effect of CO2 on climate
- Identify the indirect effects due to carbon cycle constraints on surface water, carbon, and energy fluxes
- Develop and improve methodology for observing and detecting these effects, and how they change over time
Projects managed under this program’s auspices assess carbon components affecting the climate. Research results lead to improved models for predicting ecosystem carbon fluxes, ecosystem-climate feedbacks, and radiative forcing of climate by greenhouse gases and aerosols.
Key sponsors and resources for this program are DOE-BER Atmospheric System Research Program, the ARM Climate Research Facility, and databases at ARM, NOAA, AmeriFlux, and Fluxnet.
