The U.S. Department of Energy requires all contractors using LINUX-based computers to implement RedHat Enterprise Version 3.0 (RHE V3.0) software as their standard operating system. This applies to computer systems running at the ARM Climate Research Facility’s Southern Great Plains (SGP) locale, and implementation there is planned for late 2004. All existing software packages will…

Jimmy Ivanoff, lead operator at the North Slope of Alaska ARM locale, launches a radiosonde during Phase II of the AIRS validation activity. ARM file photo. Phase II of the ARM Program’s special series of radiosonde flights, coordinated with overpasses of the National Aeronautics and Space Administration’s “Aqua” satellite, began in September 2003 at all…

In October 1997, the ARM Program entered into a contract with the University of Alaska-Fairbanks to obtain image data covering the ARM Climate Research Facility’s North Slope of Alaska (NSA) locale. Image data taken by an advanced very high resolution radiometer (AVHRR) are collected by a satellite receiver at Fairbanks and, up until February 2004,…

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…
