Scientists from around the world use data from the U.S. Department of Energys Atmospheric Radiation Measurement (ARM) Climate Research Facility to study the interactions between clouds, aerosol, and radiation. At the American Meteorological Societys Annual Meeting, held this year in New Orleans from January 23-27, scientists are presenting dozens of <a href="/news/ams2012">oral and poster sessions</a> describing their research using data from the user facility.

Between November 2010 and November 2011, a handful of meteorological instruments&mdash;including Doppler sodar, ultrasonic anemometers, and one of ARM's radar wind profilers&mdash;gathered massive amounts of data for the Columbia Basin Wind Energy Study. To ensure that the data collected represent conditions experienced by real wind plants, the instruments were placed next to an operating [...]

The ARM Climate Research Facility once again took part in the American Geophysical Union (AGU) Fall Meeting, which attracted an estimated 20,000 attendees, with 12,000 posters and 6,000 oral presentations&mdash;a growth of more than 11 percent from last year's meeting. During the meeting, held from December 5-9 in San Francisco, nearly 500 visitors stopped [...]

<strong>Reminder:</strong> The ARM Climate Research Facility is now accepting applications for use of an <a href="http://www.arm.gov/sites/">ARM mobile facility (AMF), the ARM aerial facility (AAF), and fixed sites</a>. Proposals are welcome from all members of the scientific community for conducting field campaigns and scientific research using the ARM Facility. Preproposals are due February 1, 2012.

Between May and October 2011, the ARM Southern Great Plains site hosted a guest instrument for the U.S. Geological Survey (USGS) called the High Dynamic Range All-Sky Imaging System, or HDR-ASIS. This instrument combines an upward-looking (or zenith-pointing) temperature-controlled digital camera with HDR imaging techniques to capture hemispherical images of the sky dome. HDR imaging [...]

On November 15, ARM communications staff and scientists participated in the third annual Chief Joseph Middle School Science Night in Richland, Washington. They shared with students how to build their own anemometer, handed out activity booklets and lesson plans to interested teachers, students, and parents, and brought along Professor Polar Bear and the climate kids [...]

In October 2011, the ARM North Slope of Alaska site in Barrow welcomed a new eddy correlation (ECOR) flux measurement system and complementary surface energy balance system (SEBS), as well as a change to its baseline instrument suite: a methane gas (CH4) sensor for measurements of greenhouse gases emanating from the surrounding tundra. The [...]
