CLASIC Discussed at Workshop in Oklahoma
In June 2007, ARM led the multi-agency Cloud and Land Surface Interaction Campaign (CLASIC) conducted at the ARM Southern Great Plains site. With scientists beginning to analyze the data, the Cooperative Institute for Mesoscale Meteorological Studies at the University of Oklahoma hosted a workshop on March 26-27 for participants of CLASIC and others interested in…

Aerosols and Clouds: A Complex Climate Connection
In April 2008, scientists sponsored by the U.S. Department of Energy’s Office of Science will use a heavily instrumented research aircraft based out of Fairbanks to obtain cloud and aerosol measurements in the sky over Barrow, Alaska. Researchers will use the data to examine cloud composition and resulting effects on climate cycles.

New Radiometer Tested for Measuring Thin Clouds
A Thin-Cloud Rotating Shadowband Radiometer (TCRSR) has completed a month of testing at the ARM Southern Great Plains (SGP) site to assess its ability to simultaneously retrieve measurements of the size and density of cloud droplets in “thin” clouds, i.e., clouds with water content less than 100 grams per square meter. Both of these properties…

New ARM PI Product—Merged MMCR and WSR-88D Data Sets
A new ARM Principal Investigator (PI) product—Merged MMCR and WSR-88D Data sets (PI:X. Dong)—is now available at the ARM Climate Research Facility Data Archive. This data set merges Millimeter Wavelength Cloud Radar (MMCR) reflectivity data with National Weather Service precipitation radar (WSR-88D) observations to provide improved radar reflectivity profiles in situations where the MMCR signal…

Scout Team Scopes Out Sites for 2009 Field Campaign in Chile
In February, a four-person scout team spent two weeks in Chile conducting initial site surveys and meeting with local contacts in preparation for phase two of the Radiative Heating in Underexplored Bands Campaign, or RHUBC-II. Planned to take place on the Chajnantor plateau between August and October 2009, this offsite field campaign will use spare…

Radar Focus Group Zeroes in on Data Quality
In 2007, ARM established a Radar Focus Group to address strategic needs related to the use of radars as a key component of the ARM instrument suite. Based on needs identified by this group, a smaller team of science, engineering, and data quality staff met in early February in Santa Barbara, California, to determine methods…
