Members of the Atmospheric Radiation Measurement (ARM) user facility’s science team are major contributors to radiation and cloud research. Scientists and investigators using ARM publish about 150 peer-reviewed journal articles per year, and ARM data are used in many studies published by other scientific organizations. These documented research efforts represent tangible evidence of ARM’s contribution to advances in almost all areas of atmospheric radiation and cloud research.

Learning about drizzle from a Doppler cloud radar
9 February 2019
Fridlind, Ann M.
Supported by:
Research area: Cloud Processes
Drizzle from shallow clouds over global oceans can lead to profound changes in atmospheric particle concentrations, cloud cover, and sunlight reaching the ocean surface, but how the process gets started remains surprisingly poorly understood. Shown here is a first use of vertically-pointing radar measurements over the Azores to evaluate and [...]
Marine boundary-layer aerosol in Eastern North Atlantic: seasonal variations and key processes
24 December 2018
Wang, Jian

Research area: Cloud-Aerosol-Precipitation Interactions
Here we elucidate the key processes that drive marine boundary-layer (MBL) aerosol size distribution in the Eastern North Atlantic (ENA) using long-term measurements. The governing equations of particle concentration are established for different modes.
Evaluating soil moisture feedback on convective triggering
21 December 2018
Williams, Ian N.
Supported by:
Research area: General Circulation and Single Column Models/Parameterizations
The sign of the feedback of soil moisture on convective triggering varies with tropospheric state, challenging its quantification. Using model experiments to classify tropospheric states, this research identified positive and negative feedbacks in observations and climate models, and explored modeled feedback sensitivity to convective and land-surface parameterizations.
