Research Highlights

 

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.

What controls variations in atmospheric humidity, CAPE, and precipitation?

21 January 2021

Romps, David

Supported by: ARM ASR

Research area: Atmospheric Thermodynamics and Vertical Structures

Analytic solutions are derived for the relative humidity, lapse rate, and precipitation rate of an atmospheric column with mean ascent. By comparison with ARM data, it is shown that these solutions cannot be used to explain variations of humidity, CAPE, and precipitation as has been argued in the literature, but [...]

Considering irrigation improves simulated mesoscale convective systems and low-level jets

20 January 2021

Fast, Jerome D

Supported by: ASR

Research area: General Circulation and Single Column Models/Parameterizations

The fact that climate models tend to predict an overly warm and dry climate in the central United States has been a persistent issue in the field. Previous studies have proposed possible explanations for this bias, such as underestimation of the evaporative fraction and overestimation of shortwave radiation. This highlight [...]

Comparison is key to validating aircraft measurement data sets

15 January 2021

Schmid, Beat

Supported by: ARM

Research area: Aerosol Processes

As more studies focus on how atmospheric properties in the Amazon basin change in space and over time, obtaining quality-controlled measurements is essential. However, the challenges of airborne operations, especially with multiple aircraft collecting data in the same area, makes direct comparison studies fundamental, but rare. A field campaign led by [...]
