As shown in this aerial photo of Oliktok Point, Alaska, the USAF Long Range Radar Station—also known as Dew Line Station—is situated at the edge of the Arctic Ocean. Instrumentation for the ARM Program’s M-PACE experiment will be located just south of the station, near the aircraft hangar. (Photo courtesy of Aeromap U.S.) After more…

As shown in this partial screen capture, the Real Time Monitoring and Control feature displays data that allows local observers to quickly check the status of the instrument system. ARM file image. As part of ongoing effort to upgrade data loggers and logging systems throughout the ARM Climate Research Facility, new Campbell Loggers (version CR23X)…

April was a record month for the ARM Climate Research Facility Data Archive, with 1.2 terabytes (or 1.2 trillion bytes) of data delivered to customers, and about 1 terabyte of data delivered and stored in the Archive. This impressive statistic represents 450,000 files retrieved—roughly double the largest previous month of data distribution! This trend continued…

In April, operations personnel completed a series of cost-saving data communication changes at the ARM Climate Research Facility Southern Great Plains (SGP) locale. The T-1 telephone lines at the four SGP boundary facilities were replaced with satellite dish technology. This change still allows large data sets to be transferred at acceptable bandwidth but at substantial…

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…
