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.

Relationships between cloud and land surface fluxes across cumulus and stratiform coupling

12 April 2024

SU, Tianning; Li, Zhanqing

Supported by: ARM ASR

Research area: Cloud Processes

In our study, we systematically explored the multifaceted relationships between land surface fluxes and low-cloud formation across different cloud regimes. By analyzing merged data of the long-term ARM ground observations with coupling diagnostics, we identified distinct cloud-land interaction patterns contingent upon different coupling regimes and critically assessed the capabilities of [...]

Interpretable and physics-aware neural networks improve modeling of turbulence near the surface

22 March 2024

Ovchinnikov, Mikhail; Wang, Aaron

Supported by: ASR

Research area: Atmospheric Thermodynamics and Vertical Structures

Turbulence near the Earth’s surface effectively transports momentum, heat, and moisture into the atmosphere. However, a universal model to accurately represent these turbulent fluxes in various flows does not exist. When the turbulence is driven by a vertical temperature gradient and thermal convection, as in the Rayleigh-Bénard convection, traditional turbulence [...]

Diurnal cycle of aerosol indirect effect for warm boundary-layer clouds explained by cloud memory

21 March 2024

Zheng, Xue

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Warm boundary-layer clouds in the Eastern North Atlantic (ENA) region exhibit notable diurnal variations in cloud properties. However, the diurnal cycle of the aerosol indirect effect (AIE) for these clouds remains poorly understood. This study reveals a “U-shaped” daytime variation of AIE with clouds more susceptible to perturbations in the [...]
