Four new DOE Early Career Research Program award winners plan to use ARM measurements In late June, 84 scientists around the country received Early Career Research Program awards from the U.S. Department of Energy (DOE). The 54 awardees from universities will receive at least $150,000 a year for five years to further their research. The…

More findings are expected from Aerosol and Cloud Experiments in the Eastern North Atlantic Drizzling clouds are commonly seen throughout the Azores. Low clouds over the Eastern North Atlantic drizzle 80 percent of the time, according to ACE-ENA principal investigator Jian Wang. A combined ground and aerial campaign recently wrapped up in the Azores that…

Campaign is part of large international effort to improve modeling capabilities around the poles A tethered balloon is seen against the clouds in October 2016 at Oliktok Point, Alaska. During the upcoming POPEYE campaign, tethered balloons will again take to the sky over Oliktok Point to collect data within and above clouds. The Atmospheric Radiation…

Women held key roles during flight and ground campaign in the Azores Female ARM Aerial Facility staff and instrument mentors during ACE-ENA gather in front of ARM’s Gulfstream-159 (G-1) research aircraft during the winter 2018 intensive operational period. From left to right, they are: Amy Sullivan, Colorado State University; Maria Zawadowicz, Alyssa Matthews, Fan Mei,…

Graham Feingold and other theoreticians use the new tool to test model parameterizations This is the second article in a series of case studies. To some of us, “lasso” refers to a stiff loop of rope handy for throwing. To statisticians, it is a way of doing regression analysis. LASSO case studies currently bundle data…

An active modeler calls himself ‘an evangelist’ for ARM data This is the sixth article in a series of profiles on members of the ARM User Executive Committee (UEC).

MARCUS, MICRE field campaigns are part of effort to understand Earth system processes in region During a MARCUS voyage in March 2018, the Aurora Australis makes its way toward Macquarie Island, the location of the MICRE field campaign. The Southern Ocean is one of the most remote—and stormiest—places on Earth. It also has significant influence…

New LASSO Data Bundles Help Close the Observation-Simulation Gap Thanks to LASSO, a cloud model simulation (above) can now more easily than ever be compared with observational data. Viewed from high above, Earth displays three color palettes that are climatologically significant. Both the brown-green land and the ice-free, deep blue oceans absorb light. Clouds, fleeting…

The National Oceanic and Atmospheric Administration scientist and his team investigate cloud behaviors with a dynamical systems perspective This is the fifth article in a series of profiles on members of the ARM User Executive Committee (UEC). Graham Feingold, an ARM User Executive Committee member, is a research scientist at the NOAA Earth System Research…
