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.

Formation and Evolution of Tar Balls from Northwestern US Wildfires
Sep 12, 2018       
Wildfires are major sources of organic and black carbon aerosol particles and tar balls -- a type of brown carbonaceous particle apparently unique to biomass burning -- are under-recognized constituents of wildfire emissions. To help quantify the contribution of biomass burning (BB) to aerosol radiative forcing, the U.S. Department of Energy’s Atmospheric Radiation Measurement [...]

Understanding the Bubbly Nature of Cumulus Convection
Aug 20, 2018       
Recent observations and detailed, high-resolution numerical modeling studies have indicated the thermal-like, bubbling nature of moist convection. Using theoretical insights and high-resolution numerical modeling, researchers at the National Center for Atmospheric Research and the Naval Postgraduate School developed a mathematical expression for the ascent rate of these thermals comprising convective clouds, as well as the [...]

Observing Clouds in 4D with Multi-view Stereo Photogrammetry
Aug 17, 2018       
Shallow cumulus clouds – the cotton-ball clouds that drift overhead on partly cloudy days – are hard to observe and, therefore, hard to model and predict.  By deploying a 12-km-diameter ring of cameras, these clouds are now being observed in fine detail using stereo reconstruction.

Heterogeneity in Warm‐season Land‐atmosphere Coupling over the U.S. Southern Great Plains
Aug 09, 2018       
Land-atmosphere (LA) coupling has been identified to play an important role in climate through its impacts on the energy and water cycles in the Earth system. The driving mechanisms of how the land states (e.g., soil wetness and vegetation) impact the surface turbulent fluxes are not well understood. The United States Southern Great Plains (SGP) [...]

Water Vapor Turbulence Profiles of the Convective Boundary Layer over the ARM TWP Site
Aug 09, 2018       
Turbulence in the convective boundary layer (CBL) is often described by its statistical properties, including the vertical profiles of mean (first moment), variance (second moment), and skewness (third moment). Accurately representing turbulence in numerical models is critical because turbulence mixes mass, momentum, and energy within the CBL, and since turbulence works on a range of [...]
