Climate and Environmental Sciences Division (CESD)

Atmospheric System Research (ASR) Program

Program Mission

The mission of ASR (http://asr.science.energy.gov/), in partnership with the Atmospheric Radiation Measurement (ARM) Climate Research Facility, is to quantify the interactions among aerosols, clouds, precipitation, radiation, dynamics, and thermodynamics to improve fundamental process-level understanding, with the ultimate goal to reduce the uncertainty in global and regional climate simulations and projections.

Program Approach

To accomplish this mission ASR utilizes continuous long-term datasets that provide measurements of radiation, aerosols, clouds, precipitation, dynamics, and thermodynamics over a range of environmental conditions at several fixed and mobile ARM sites situated in climatically diverse locations. These datasets are supplemented with laboratory studies and shorter-duration ground-based and airborne field campaigns to target specific atmospheric processes under a diversity of locations and atmospheric conditions. The long- and short-term data, together with models, are employed to understand and parameterize the processes that govern the atmospheric components and their interactions over all pertinent scales. Finally, ASR seeks to develop integrated, scale-bridging test-beds for model parameterizations that incorporate this process-level understanding of the life cycles of aerosols, clouds, and precipitation in numerical models.

Program Funding Opportunity Announcements

Announcements are posted on the DOE Office of Science Grants and Contracts Web Site and at grants.govExternal link Information about preparing and submitting applications, as well as the DOE Office of Science merit review process, is available at the DOE Office of Science Grants and Contracts Web Site.   For current announcements, visit BER Funding Opportunities.

Data Sharing Policy

Funding of projects by the program is contingent on adherence to the BER data sharing policy.

Program Research Activities

The aerosol-cloud-radiation continuum and its role in the climate system are complex with many physical and dynamical facets. The ASR program's research is centered on studying the key interactions among these processes that must be well understood to improve the representation of aerosol, cloud, radiation, and precipitation processes in climate models. Currently supported science research areas include Cloud Life Cycle, Aerosol Life Cycle, and Cloud-Aerosol-Precipitation Interactions.

Collaborations with CESD Climate Modeling Programs: in order to promote efficient implementation of improved atmospheric process understanding into DOE-supported coupled climate models, ASR participates in model activities with the division's modeling programs. These include the CAPT project ((http://www-pcmdi.llnl.gov/projects/capt/)External link).
