Members of ARM's science team are major contributors to radiation and cloud research. ARM investigators publish about 150 refereed 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. Below is a selection of summaries highlighting recently-published ARM research. The entire collection of ARM Research Highlights can be accessed using the sorting buttons at right.

Aerosols have a strong effect on climate through their potential to modify the properties of warm clouds. An increase in aerosol loading could reduce drizzle production; modulate the stability of the boundary layer; and change cloud properties, lifetime, and extent, which is referred to as the second aerosol indirect effect. Recent studies showed that global [...]

It is hypothesized that specific cloud populations at different stages are essential to the initiation and maintenance of the Madden-Julian Oscillation (MJO). In particular, the occurrence of shallow convection that then transitions to mid-level convection before the active phase of the MJO is thought to provide lower-level heating that then promotes large-scale moisture convergence necessary [...]

The state of the land can influence surface energy and moisture fluxes, boundary-layer clouds, and regional convection and precipitation, especially in summer when it couples more intensely with the atmosphere. Therefore, investigations of the cloud life cycle over continents need to consider the role played by land-atmosphere interactions. Coarse-resolution global climate models tend to simulate a [...]

For decades, researchers have intensively studied observationally based cloud fraction estimates to better understand current climate change and predict future climate variability. In this study, observationally based cloud fraction estimates from six different platforms (three ground-based estimates and three satellite-based estimates) are compared.

The thermodynamic structure of the atmospheric boundary layer (BL; the lowest 1-3 km of the atmosphere) rapidly changes due to a wide range of processes, and many studies require accurate profiles of temperature and water vapor at high time-resolution in order to understand the processes at work in the BL. These profiles can be derived [...]
