Preparations Underway for 2007 ARM Mobile Facility Deployment in Germany
In collaboration with researchers from the University of Hohenheim (Germany), the ARM Mobile Facility (AMF) will be deployed in 2007 as part of the Convective and Orographically-induced Precipitation Study (COPS), taking place in the Black Forest area of Germany. Orographic precipitation refers to rainfall resulting from atmospheric uplift (convection) in mountainous terrain. The COPS region…

Sunphotometer to Obtain Additional Aerosol Data in Niamey
In early August, a new Cimel sunphotometer (CSPHOT) was deployed at the ARM Mobile Facility site in Niamey, Niger, as part of the ongoing RADAGAST field campaign. The CSPHOT measures the solar and sky radiance at various wavelengths in the visible and near-infrared spectrum (340, 380, 440, 500, 670, 870, 936, 1020 nm). From these…

New Operations Status System Improves Tracking, Reporting
With heavily instrumented research sites around the globe, the ARM faces a daunting operations and reporting challenge. To better track and report the status of the capabilities at these widely disbursed sites, ARM operations staff recently completed the development of a comprehensive Operations Status System (OSS). By serving as a central collection point for all…

Kids Learn About Weather at Day Camps in June
On June 6, education and outreach staff from the ARM Southern Great Plains (SGP) site spent four hours helping local Girl Scouts earn their Weather Badges. Nearly 100 scouts participated in the day camp held outdoors at Reeves Park in Norman, Oklahoma. Seven “learning stations” were staffed by female volunteers ranging from professional meteorologists to…

Infrared Sky Imager Takes a Shot in the Dark
Imaging technologies help scientists correlate and compare data retrieved by sensors and lasers against visual data. One such technology used by ARM researchers is a Total Sky Imager (TSI), which provides real-time processing and full-color display of daytime sky conditions. However, to get the continuous picture of cloud life cycles needed for critical scientific analysis,…

“VAPs” Define Key Properties at ARM Sites
Despite extensive instrumentation deployed at the ARM sites, some quantities of interest remain either impractical or impossible to measure directly or routinely. For this reason, some ARM Program science needs are met through the analysis and processing of existing data products into “value-added” products, or VAPs. Earlier this year, the Merged Sounding VAP was used…

Data From Rotating Shadowband Spectroradiometer Now Available in Data Archive
After refinements based on a series of successful field trials, the latest Rotating Shadowband Spectroradiometer (RSS) joins the collection of permanent ARM instruments at the ARM Southern Great Plains (SGP) site. The current RSS—known as the RSS105—is deployed at the SGP Central Facility and is the first commercially built RSS manufactured by Yankee Environmental Systems,…

Comprehensive Instrument Validation Campaign Concludes
After almost four years, the last soundings in the final phase of the Atmospheric Infrared Sounder (AIRS) validation program were completed on May 14 at the ARM Tropical Western Pacific locale. Since late July 2002, operators at the ARM sites launched approximately 2600 radiosondes (or sondes) in support of validation studies for the AIRS instrument…
