Research Highlights


Members of the Atmospheric Radiation Measurement (ARM) user facility‚Äôs 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.

Recent Highlights

Combining space and ground measurements for more accurate rainfall estimates

20 November 2018

Jakob, Christian; Collis, Scott Matthew

Supported by: ARM ASR

Research area: Cloud Distributions/Characterizations

A new integrated radar calibration technique using a combination of radar returns from fixed objects on the ground and satellite measurements yields a long-term radar reflectivity calibration with a much higher accuracy than previously possible.

The role of cloud top radiative cooling in marine stratocumulus

19 November 2018

Li, Zhanqing; Zheng, Youtong

Supported by: ARM ASR

Research area: Cloud Processes

Everything cools radiatively. This study investigates how the cooling of oceanic low clouds drives their physical properties including (1) the bases of clouds, (2) surface energy fluxes, and (3) their coupling with sea surfaces.

Improved convection parameterization reduces double ITCZ biases

11 November 2018

Zhang, Guang

Supported by: ARM ASR

Research area: General Circulation and Single Column Models/Parameterizations

This study demonstrates for the first time that improvements in convection parameterization can eliminate the double intertropical convergence zone (ITCZ) biases in all seasons, including boreal winter and spring in the NCAR CESM. It corroborates that convection parameterization is the primary contributor to the double ITCZ bias and provides a [...]
