Funding Opportunity Announced for Regional and Global Climate Modeling and ASR
The U.S. Department of Energy’s Office of Science is now accepting applications for Office of Biological and Environmental Research (BER) grants on topics related to the “Reduction of Tropical Cloud and Precipitation Biases in Global High Resolution Models” under the Regional and Global Climate Modeling (RGCM) and Atmospheric System Research (ASR) programs. Priority will be…

Fiscal Year 2012 Funding Opportunity Announced for ASR
Updated: February 7, 2012. In response to a question raised by potential applicants, DOE has modified the text of DE-FOA-0000647 to correct an unintended limitation of scope of the announcement. Although a complete revised version of the Funding Opportunity Announcement (FOA) has been posted, the only change is in one sentence in the original text…

Old Meets New: Comparison of Aerosol Observing Systems Underway
With funding from the American Recovery and Reinvestment Act, scientists at Brookhaven National Laboratory built a handful of new Aerosol Observing Systems for the ARM Facility in the past two years. One of these new systems, assigned to the second ARM Mobile Facility (AMF2), is temporarily located at the ARM Southern Great Plains site in…

Data Collection from Mobile Facility on Gan Island Suspended
Due to sudden unrest in the Maldives in early February, operations of the ARM Mobile Facility on Gan Island were suspended on February 9, 2012, and all instruments have been secured and powered down. If the situation stabilizes, AMF operations for the ARM Madden-Julian Oscillation Experiment, or AMIE, which began in October 2011, may resume…

Expanding Horizons for Climate Research
In 2012, the Atmospheric Radiation Measurement (ARM) Climate Research Facility begins outfitting two new remote climate observation sites at opposite ends of the climate spectrum—one in the harsh arctic environs of Oliktok Point, Alaska, and the other in the mild marine climate of the Azores, in the North Atlantic Ocean. Scientists will use measurements from…

Five Years of Radiatively Important Parameters Best Estimate (RIPBE) Data Now Available
Scientists use detailed state-of-the art radiative transfer models to understand the radiative impact of clouds and aerosols on the Earth’s radiation budget, evaluate remote-sensing retrievals of cloud and aerosol properties, and develop and evaluate simpler radiative transfer models for inclusion in cloud and climate models. The ARM suite of instruments measures all of the radiatively…

It’s Official Now—Cloud Microphysical Properties Value-Added Product Changes Status
The Continuous Baseline Microphysical Retrieval (MICROBASE) value-added product (VAP) has been released as an official ARM VAP. Data from April 1998 through December 2009 are now available for the Southern Great Plains, North Slope of Alaska, and Tropical Western Pacific sites. Historical updates will be provided whenever additional data become available. MICROBASE is a baseline…

News Tips from AMS 2012
Scientists from around the world use data from the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility to study the interactions between clouds, aerosol, and radiation. At the American Meteorological Society’s Annual Meeting, held this year in New Orleans from January 23-27, scientists are presenting dozens of oral and poster sessions describing…

Wind Profiler Completes Offsite Campaign
Between November 2010 and November 2011, a handful of meteorological instruments—including Doppler sodar, ultrasonic anemometers, and one of ARM’s radar wind profilers—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 wind…

Mapping for Precipitation Radar Data Ready for Evaluation
The first-ever 4-dimensional ARM data product, called Mapped Moments to a Cartesian Grid (MMCG), is now available for testing by the science community. Covering all major precipitation events during the Midlatitude Continental Convective Clouds Experiment, the MMCG is derived from scanning C-band ARM precipitation radar (C-SAPR) data. This value added product (VAP) was developed to…
