Cloud Processes Group
The Cloud, Aerosol, and Complex Terrain Interactions (CACTI) experiment in the Sierras de Córdoba mountain range of north-central Argentina is designed to improve understanding of cloud lifecycle and organization in relation to environmental conditions so that cumulus, microphysics, and aerosol parameterizations in multi-scale models can be improved.
The Atmospheric Radiation Measurement (ARM) West Antarctic Radiation Experiment (AWARE) aims to gain insight into the factors behind recent climate change in West Antarctica by quantifying the role of changing air masses on the surface energy balance. The field campaign will use some of the most advanced atmospheric research instrumentation to conduct cloud, radiative, and aerosol observations. The project is cosponsored by the U.S. Department of Energy's Office of Science and the National Science Foundation. Andrew Vogelmann is a Co-Investigator.
MAGIC—the Marine ARM (Atmospheric Radiation Measurement) GPCI Investigation of Clouds—is the first deployment of the ARM Mobile Facility on an ocean-going vessel, the Horizon Lines container ship Spirit. Ernie Lewis was the lead scientist for the campaign that obtained unprecedented data on the stratocumulus-to-cumulus transition via regular transects made between Los Angeles and Hawaii from October, 2012 to January 2013 and from May to September, 2013.
MC3E—the Midlatitude Continental Convective Cloud Experiment—is a joint field program involving ARM and NASA Global Precipitation Measurement Program investigators that was conducted in south-central Oklahoma from April to June 2011. Its goal was to collect a comprehensive set of surface-, aircraft- and satellite-based observations to target processes important for the parameterization of convection in large-scale models. Mike Jensen was the Principal Investigator and Scott Giangrande a Co-Investigator.
RACORO—Routine AAF Clouds with Low Optical Water Depths (CLOWD) Optical Radiative Observations—is a first-of-a-kind, extended-term cloud aircraft campaign conducted to obtain an in situ statistical characterization of continental boundary-layer clouds. Andy Vogelmann was the lead scientist of the campaign that was coordinated by the Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) and operated over the ARM Southern Great Plains site.
