ARM Climate Research Facility – Highlights at AMS Annual Meeting
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 this year’s meeting of the American Meteorological Society, scientists present results of their research, using ARM data for long-term analyses, model comparisons, and measurement validation…

Cirrus Clouds Hold Clues to Climate
On January 4, scientists sponsored by ARM began a five-month aircraft campaign to gather data from cirrus clouds in the skies above Oklahoma. Using an instrumented Learjet 25 research aircraft, their goal is to obtain a new and comprehensive set of in-cloud, or “in situ,” measurements about the size and number of ice crystals that…

Highlights from DOE Scientific User Facility at AGU Fall Meeting 2009
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 this year’s American Geophysical Union (AGU) Fall Meeting, scientists will present oral and poster sessions of their research using these data for long-term analyses, model…

Thumbs-Up for Radar Design Reviews—Key Recovery Act Milestone
In November, ARM completed a series of successful preliminary design reviews for new scanning cloud and precipitation radars. This progress marks a key milestone for deploying 18 new radars—unheard of in the climate research arena—throughout the user facility through funding from the American Recovery and Reinvestment Act.

Nature Magazine Features Mobile Facility Deployment In China
A news feature published in Vol. 461 of Nature magazine covers the ARM Mobile Facility deployment in China. In 2008, with all eyes on Beijing during the Olympics, the ARM Mobile Facility quietly obtained eight months of climate data from the city of Shouxian, west of Shanghai. Combined with atmospheric measurements from several other locations…

Open House Draws Crowd to ARM Climate Research Facility Display
Mild summer temperatures helped bring thousands of visitors through the gates of Argonne National Laboratory on August 29 for an open house, which featured a display about the ARM Climate Research Facility. Located in one of six very large tents in the middle of the Argonne campus, the display occupied about 50 feet by 30…

The Air is Rare Up There!
This week, on a mountain rising from Chile’s Atacama Desert, researchers launched phase two of the Radiative Heating in Underexplored Bands Campaign. The team is using a suite of sophisticated spectrometers to obtain, for the first time, simultaneous measurements from the infrared portions of the electromagnetic spectrum. These measurements will ultimately improve the mathematical formulas…

RACORO Campaign Comes to a Close
In the first long term aircraft campaign of its kind, the RACORO field campaign wrapped up flight operations on June 30. Guided by a seven-member science steering committee, the team logged 259 research hours from the skies above Oklahoma. The five-month campaign obtained a statistical data set of cloud, aerosol, radiative, and atmospheric state measurements.

Preparations Heat Up for Field Campaign in Chile
At an elevation of more than 5000 meters on the Atacama Desert in Chile, the site for the second phase of the upcoming Radiative Heating in Underexplored Bands Campaign is not only very high, but also remote. To reduce the potential for surprises, the science and operations team completed a comprehensive beta test at the…
