Following four weeks of data acquisition, the Arctic Winter Water Vapor Intensive Operational Period (IOP) at the ARM Climate Research Facility’s North Slope of Alaska (NSA) locale was completed the weekend of April 9, 2004. In collaboration with the National Oceanic and Atmospheric Administration’s Environmental Technology Laboratory (ETL), the major goal of this IOP was…

Dr. Ari Patrinos answers questions from the audience at the conclusion of his plenary address during the ARM Science Team Meeting in Albuquerque, New Mexico, in March 2004. ARM file photo. Shattering previous attendance records, 316 ARM Program participants (and a few interested visitors) from across the globe met in Albuquerque, New Mexico, on March…

In mid-March, the last of a series of new eddy covariance or “eddy correlation” (ECOR) systems was installed at the ARM Climate Research Facility’s Southern Great Plains (SGP) extended facility at Cyril, Oklahoma. This completes the replacement of the original ECOR systems initiated in 2002. In all, nine new ECOR systems have been deployed, including…

At the three ARM Climate Research Facility locales (Southern Great Plains, Tropical Western Pacific, and North Slope of Alaska), more than 260 instruments and 1,500 individual sensors operate continuously to provide uninterrupted streams of data to the ARM research community. Existing principle metrics provide information on what data is or is not available, but doesn’t…

The scientific infrastructure established by the ARM Program – heavily instrumented research sites, the ARM Data Archive, and the ARM Mobile Facility under development – is now available for use by scientists worldwide through the ARM Climate Research Facility. As a national user facility, this unique asset provides the opportunity for a broader national and…

Some of the instruments collecting data during the Arctic Winter Water Vapor IOP include ARM’s microwave radiometer profiler (left) and microwave radiometer (right), and NOAA’s ground-based scanning radiometer (middle).

In addition to providing database support to the ARM Program, the External Data Center (XDC) identifies and acquires “external” sources of data to augment the data being generated within the program. These external data are transformed from their original received form to data sets of greater value to ARM researchers. These transformations may involve subsetting,…

Thanks to a collaboration with Barrow Arctic Science Consortium (BASC), Starband satellite internet service to Oliktok – located on the eastern side of ARM’s North Slope of Alaska (NSA) site – is being established to support the ARM Program’s Mixed-Phase Arctic Cloud Experiment (M-PACE). With various modes of 50kb up/500kb down data transfer available, this…

The overall goal of the ARM Education and Outreach team is to develop basic science awareness and increase critical thinking skills in environmental science and climate change for K-12 students located near ARM sites at the North Slope of Alaska, Southern Great Plains (Oklahoma), and Tropical Western Pacific. One of the tools the ARM education…
