Research Highlights

Highlights will be written for high-level accomplishments and published journal articles of ASR research. Each PI should submit one highlight per fiscal year. To send in a research highlight, please use the submittal form.

For highlights from research done under ARM and ASP, see http://www.arm.gov/science/highlights and http://www.asp.bnl.gov/#HIGHLIGHTS, respectively.

Improving Water Vapor Continuum Absorption and Its Impact on a GCM Simulation
May 15, 2012        Funded By:  ARM ASR
Improving the accuracy in radiative transfer codes used within general circulation models (GCMs) is an important climate research priority in the U.S. Department of Energy. Our understanding of the gaseous absorption in the mid-infrared (i.e., from 3–16 µm), which underlies these radiation codes, has undergone many important improvements due to the well-characterized radiation measurements [...]

Development and Recent Evaluation of the MT_CKD Model of Continuum Absorption
May 14, 2012        Funded By:  ARM ASR
Absorption and emission of radiation by atmospheric gases are important drivers of Earth’s climate. Due to the inherent physical properties of water vapor molecules and their abundance in the atmosphere, radiative processes due to water vapor play an especially prominent role. Absorption/emission by water vapor molecules occurs at discrete spectral locations, called absorption lines, and [...]

CAM5 Shows Reasonable Aerosol First Indirect Effects on Non-Precipitating Low Liquid Clouds
May 02, 2012        Funded By:  ARM ASR
The Intergovernmental Panel on Climate Change (IPCC) listed the indirect effects of aerosols on climate change as one of the largest uncertainties in current climate models. Evaluating distinct components such as the first indirect effect can help identify where problems occur and where model representations are more robust, and can thus lead to a narrowing [...]

Regional Controls on Ozone Precursors Will Have Different Impacts on Future Climate
Apr 16, 2012        Funded By:  ASR
Ozone precursor emissions influence regional and global climate and air quality through changes in tropospheric ozone and oxidants, which also influence methane (CH4) and sulfate aerosols.

Mexico City Carbon-Containing Particle Composition Simulated
Apr 12, 2012        Funded By:  ARM ASR
A team of researchers simulated the production and composition of secondary organic aerosols (SOA) in Mexico City pollution outflow plume. They found that the SOA loading several days downwind was more than three times that leaving the city. These results suggest significant radiative impacts of Mexico City SOA in the outlying regions, several hundred kilometers [...]
