Radon Measurements to Help Scientists Estimate Carbon Dioxide Exchange
In November, ARM scientists and researchers from the National Oceanic and Atmospheric Administration’s Climate Monitoring and Diagnostics Laboratory began a collaborative field campaign at the ARM Southern Great Plains (SGP) site. The science objective of the Radon Measurements of Atmospheric Mixing (RAMIX) field campaign is to quantify the mixing rate of air between the surface…

Postdoctoral Fellowship in Cloud Modeling Open at the University of Melbourne
The University of Melbourne invites applications from suitably qualified persons to fill a new position in cloud modeling. This Postdoctoral Fellowship is funded by the Australian Research Council to conduct cloud-scale modeling of tropical convection that was observed during the recent Tropical Warm Pool International Cloud Experiment (TWP-ICE). TWP-ICE was a large international field experiment…

ARM Mobile Facility Moves to China in 2008 for Study of Aerosol Impacts on Climate
China generates exceptionally high amounts of aerosol particles whose influence on the atmosphere has been detected across the Pacific Rim. In the Yangtze River delta in southeast China, these high aerosol loadings result from both natural and manmade sources. With a subtropical climate characterized by marine monsoons, atmospheric conditions in this region change quickly but…

ARM External Data Center Celebrates Ten Years of Service
In celebration of its tenth year of operation, the ARM External Data Center (XDC), which is managed by Brookhaven National Laboratory, was recently recognized for its outstanding contribution to the scientific user community. The XDC collects and processes data from other climate monitoring and research programs to supplement the data collected at the ARM sites.…

Diffuse Irradiance Study to Set Measurement Standard
Scientists use an assortment of sophisticated remote-sensing instruments to obtain measurements of cloud and other atmospheric properties for climate research. A pyranometer is an instrument that measures how much solar radiation is scattered by molecules and particles in the atmosphere. The pyranometer is mounted to “solar trackers” that follow the path of the sun, continuously…

Educational Kiosk Installed at ARM Site in Nauru
Surround by the Pacific Ocean, the Republic of Nauru is one of three sites that make up the ARM Tropical Western Pacific (TWP) locale. With a livelihood and economy driven largely by a dependence on environmental conditions, inhabitants of the small island of Nauru have a keen understanding of the importance of weather and climate.…

Arctic Research on Senator’s Screen
In late October, U.S. Senator Ted Stevens (R-Alaska), his staff, and executive staff from the Arctic Slope Regional Corporation (ASRC) visited the ARM North Slope of Alaska (NSA) site in Barrow. Site operations staff showed the visitors around the site’s instrument shelter and explained how scientists use data from the site for research on climate…

Radar Wind Profiler Upgrades Optimize Performance, Increase Reliability
Radar wind profilers (RWPs) provide hourly measurements of wind speed and direction from 100 m to 5 km above the ground. Between 1992 and 1996, four 915 MHz 9-panel radar wind profilers (RWPs) were deployed at the ARM Southern Great Plains (SGP) site, followed by one more at the North Slope of Alaska (NSA) site…
