Inside the instrument shelter, the MMCR data system collects radar spectral data and processes these into reflectivity, vertical velocities, and spectral width. ARM file photo. As a result of upgrades to the Millimeter Wave Cloud Radar (MMCR) processors (see http://www.arm.gov/acrf/updates051504.stm#nsammcr) at the ARM Climate Research Facility Southern Great Plains (SGP) and North Slope of Alaska…

Real-time data from all three of the ARM Climate Research Facility sites (North Slope of Alaska, Southern Great Plains, and Tropical Western Pacific) are collected and processed at the ARM Climate Research Facility Data Management Facility (DMF) each day. Processing involves the application of algorithms for performing simple averaging routines, qualitative comparisons, or more complicated…

A CIMEL sunphotometer, similar to this one in Tinga Tingana, Australia, will be installed at the ARM Climate Research Facility Darwin site. Photo courtesy of NASA Goddard Space Flight Center.

NASA’s WB-57F research aircraft can carry an instrument payload up to 6,000 lbs. Image courtesy NASA. In late April, scientific collaborators at the National Aeronautics and Space Administration (NASA) carried out two high-altitude flights over the ARM Climate Research Facility Southern Great Plains (SGP) central facility. The purpose of these flights was to use a…

In mid-April, hardware and software upgrades to the millimeter wave cloud radar (MMCR) at the ARM Climate Research Facility’s North Slope of Alaska (NSA) were completed. Hardware upgrades included replacing the OS/2 and Solaris computers with two Windows 2000 computers. One of these computers is for the MMCR radar. It now has a new digital…

The CIMEL sunphotometer takes sky radiance measurements during daylight hours, when the sun is above horizon. ARM file photo. In early May, a CIMEL sunphotometer owned by the National Aeronautics and Space Administration (NASA) was re-installed at Barrow, Alaska, one of two research sites that make up the ARM Climate Research Facility’s North Slope of…

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,…
