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.

Melting layer attenuation at Ka- and W-bands as derived from multi-frequency radar Doppler spectra observations

12 August 2019

Moisseev, Dmitri N

Supported by: ARM

Research area: Cloud Processes

While the melting layer is a relatively narrow layer in precipitation systems, it has a significant impact on telecommunication and remote-sensing applications. For spaceborne and ground-based radar measurements, unaccounted attenuation in the melting layer may cause significant errors in retrievals of rainfall rate and ice-cloud properties, respectively. There are two [...]

The Aleutian Low-Beaufort Sea Anticyclone: A climate index correlation with the timing of springtime

31 July 2019

Cox, Christopher James; de Boer, Gijs

Supported by: ARM ASR

Research area: Surface Properties

A new metric is proposed, a climate index termed Aleutian Low-Beaufort Sea Anticyclone (ALBSA), which is suitable for monitoring and studying the predictability of the timing of springtime melt in the Alaskan Arctic.

Correcting CMIP5 evapotranspiration trends and sensitivity to changing climate

31 July 2019

Sullivan, Ryan

Supported by: ARM ASR

Research area: Surface Properties

Evapotranspiration (ET) from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) simulations exhibits substantial biases, fostering little confidence in future ET projections. We develop a methodology to calculate ET offline using the models’ archived meteorological outputs: temperature (T), water vapor pressure (e), atmospheric pressure (P), and surface net [...]
