LASSO Case Study: Modeling Farmland Soils Swept Skyward
One study, aided by ARM’s high-resolution modeling activity, simulates the escalator of turbulence that moves tilled soils high enough to influence clouds Soil dusts disperse into the atmosphere when farmland is tilled or harvested or when eroded farm soils are swept around by winds. The resulting airborne particles are made of fine bits of plant…

Three New Value-Added Products Available for MOSAiC Expedition
The Atmospheric Radiation Measurement (ARM) user facility released three new value-added products (VAPs) from the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The three VAPs are Interpolated Sonde (INTERPSONDE), Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds (KAZRARSCL), and Aerosol Optical Properties (AOP). INTERPSONDE transforms sounding data from weather…

First Results From Southern Great Plains Aerosol-Ice Formation Closure Study
Findings could help improve modeling of atmospheric particles involved in ice crystal formation The formation of ice crystals in the atmosphere has fascinated scientists for centuries. Since 1900, scientists have known that ice crystals can form at temperatures that are below freezing but higher than needed for freezing pure liquid water droplets, and that airborne…

Cloud Droplet Number Concentration Product Updated
New data are available from the Droplet Number Concentration value-added product (NDROP VAP), which has been updated to use additional inputs. This will allow NDROP to be available quicker with better retrievals and to be applied to more sites and more cloudy days. Cloud droplet number concentration is an important factor in understanding aerosol-cloud interactions.…
