MAGIC Continues to Inspire Insights
Feb 08, 2016       
Because they cover so much of the Earth and reflect large amounts of sunlight, marine clouds play an especially critical role in climate and climate research. However, most non-satellite investigations of such clouds have been relatively short-term (~one month) in fairly small regions. The Marine ARM GPCI Investigation of Clouds (MAGIC) field campaign changed that by placing the second ARM Mobile Facility on the Horizon Spirit in 2012 and 2013.

Scientists Study Clouds’ Impact on West Antarctic Ice Melt
Jan 19, 2016       
It has been half a century since the West Antarctic atmosphere has been studied in detail and an “unprecedented deployment” of instruments from the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility is now delivering data that could help scientists understand how clouds affect melting glaciers.

Scientists Find Mostly Liquid Particulates over Amazon Rainforest
Dec 07, 2015       
When scientists participating in the GoAmazon 2014/2015 experiment measured the physical state of aerosols drifting over the Amazon rain forest, they found that 80 percent of the time those particles were liquid. Their findings, published in Nature Geoscience December 7, were a surprising departure from the results of a previous study.

Covering All Bases: Probing the Spectrum of Land-Atmosphere Interactions
Dec 07, 2015       
ARM-funded experiment to determine the flow of heat and moisture between Earth and air In less than a year, mile-long fiber optic cables will stretch across prairies and crop fields in Oklahoma, allowing scientists to gain the clearest picture yet of the exchange of heat and moisture between the land and the atmosphere. By determining these [...]

MC3E: A Legacy of Learning
Dec 07, 2015       
Four years after the field research campaign ended, data are yielding the secrets of storms Large storm clouds influence the Earth's climate system by redistributing heat and moisture in the atmosphere and delivering rain to the surface, yet current climate models struggle to accurately reproduce storm systems. To help resolve this issue, the U.S. Department of [...]

Taking Stock of the Atmosphere
Nov 16, 2015       
ARM-ACME VI field campaign will chart changes in greenhouse gas levels For the next year, a Cessna 206 aircraft from the Atmospheric Radiation Measurement (ARM) Climate Research Facility will sweep through the skies multiple times, skimming 500 feet above the Earth’s surface and soaring up to 17,500 feet, allowing scientists to gain an accurate picture of [...]

Getting an Inside View of Arctic Clouds
Nov 16, 2015       
Researchers investigate the polar atmosphere's unique properties On the north coast of Alaska, where the barren tundra meets the icy Arctic Ocean, Atmospheric Radiation Measurement (ARM) Climate Research Facility researchers are battling the elements to get a unique picture of the atmosphere in this rapidly changing region. At this experimental site—Oliktok Point, which lies approximately 300 kilometers [...]

Icy Arctic Proves Hot for Climate Data
Oct 05, 2015       
After a successful sixteen-week data collection campaign, scientists are ready to explore their data. In June 2015, the Atmospheric Radiation Measurement (ARM) Climate Research Facility launched the ARM Airborne Carbon Measurement V (ARM-ACME V), an aerial campaign focused on capturing data from the sky to better understand warming in the Arctic.

Nocturnal Storm Chasers Collect “Fantastic” Data Set to Improve Forecasts
Sep 14, 2015       
The 45-day Plains Elevated Convection at Night (PECAN) campaign was an intensive, all-out race by nearly 200 scientists and students to collect as much meteorological data as possible during nighttime storms on the Great Plains. Starting June 1 and literally running on adrenaline until July 16, PECAN participants worked through more than 30 nights to collect data, coming soon to the ARM Data Archive.

First Use of ARM’s New FAA-Approved Arctic Airspace
Aug 03, 2015       
New area offers opportunity to test manned and unmanned aerial systems in the Arctic After gaining Federal Aviation Administration (FAA) approval, new special-use arctic airspace will be available as a tool to conduct climate and atmospheric research and address scientific questions by gathering additional data under conditions unique to the area. Called Warning Area W-220 by the [...]

Remote Region Promotes Remote-Control Science
Aug 03, 2015       
With ice and snow in the Arctic decreasing, improving understanding of atmospheric processes at high latitudes becomes an increasingly critical task for climate scientists. Researchers are using remote-controlled unmanned aerial systems in Oliktok Point, Alaska, this summer to collect hard-to-gather data with the ultimate aim of improving climate models.

North to Alaska: Researchers Rush to Understand Warming Trend
Jun 08, 2015       
ARM-ACME V field campaign makes first science flight June 4 A group of scientists from the Atmospheric Radiation Measurement (ARM) Climate Research Facility won’t be looking for gold or oil this summer as they crisscross Alaska’s North Slope in an airplane. Instead, the ARM Airborne Carbon Measurements V (ARM-ACME V) team—led by Sebastien Biraud from U.S. [...]

Sleepless on the Great Plains
May 22, 2015       
In an effort to understand why the rain in the Great Plains falls mainly in the dark, more than 100 researchers and dozens of support staff will spend 25 sleepless nights on the ground and in the air this summer as part of the Plains Elevated Convection at Night (PECAN) field campaign. The ARM Facility will support this campaign from June 1 to July 15 through the Southern Great Plains site and an array of instrumentation.
