2013 Radar Meteorology Conference
This week, radar engineers and science colleagues are gathering in Colorado for the American Meteorological Society’s 36th Conference on Radar Meteorology. From new insights on Arctic cloud processes to innovative techniques for radar calibration, leading ARM radar experts are sharing their latest findings and advances from ARM’s global radar network for both weather and climate…

Value-Added Product Estimates Planetary Boundary-Layer Height from Radiosondes
The planetary boundary-layer (PBL) height (or mixing-layer depth) can vary significantly with time due to a number of factors including large-scale dynamics, cloudiness, convective mixing, and the diurnal cycle of solar radiation. The structure and depth of the PBL is important to a wide range of atmospheric processes including cloud formation; aerosol mixing, transport, and…

New Data Available for Precipitation Value-Added Product
The Quantitative Precipitation Experiment (QPE) value-added product (VAP) contains precipitation rates gathered by the C-band scanning ARM precipitation radar (C-SAPR). Data are now available for September 2011, covering the ARM Madden-Julian Oscillation (MJO) Investigation Experiment (AMIE). Due to some issues with the radar system a polarimetric-based estimate was not possible. Instead, a simple reflectivity rainfall…

Large-Scale Forcing Data for AMIE-Gan Available for Evaluation
The large-scale forcing data for the ARM MJO Investigation Experiment (AMIE) on Gan Island in the Maldives are now available for use and evaluation by the cloud modeling community. AMIE-Gan was conducted during the period October 2011 to March 2012 in conjunction with the Dynamics of the Madden-Julian Oscillation (DYNAMO) and Cooperative Indian Ocean experiment…

Evaluation Value-Added Product Estimates Organic Aerosol Components
Organic aerosol (OA, i.e., the organic fraction of particles) accounts for 10–90% of the fine aerosol mass globally and is a key determinant of aerosol radiative forcing. But atmospheric OA is poorly characterized and its life cycle insufficiently represented in models. As a result, current models are unable to simulate OA concentrations and properties. This…

What’s a Little Helium Among Friends?
What is white and blue, can hold 55,000 standard cubic feet (scf) of gas, and looks like it could attach to the International Space Station? A helium storage system, of course. This impressive contraption arrived at the ARM Southern Great Plains site in early June, along with 18,000 scf of helium inside—valuable stuff, considering the…
