Covering All Bases: Probing the Spectrum of Land-Atmosphere Interactions
ARM-funded experiment to determine the flow of heat and moisture between Earth and air Mile-long fiber optic cables will stretch across the Southern Great Plains site to measure the flux of heat and moisture (evaporation) rising to the atmosphere from the land. In less than a year, mile-long fiber optic cables will stretch across prairies…

MC3E: A Legacy of Learning
Four years after the field research campaign ended, data are yielding the secrets of storms Storm clouds over the C-SAPR, a dual-polarization Doppler radar used in the June 2011 MC3E field campaign. Large storm clouds influence the Earth’s climate system by redistributing heat and moisture in the atmosphere and delivering rain to the surface, yet…

Taking Stock of the Atmosphere
ARM-ACME VI field campaign will chart changes in greenhouse gas levels Scientists are taking air samples at different heights above the Southern Great Plains site in this Cessna 206 aircraft. 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…

Getting an Inside View of Arctic Clouds
Researchers investigate the polar atmosphere’s unique properties Researchers are using unmanned aerial systems to study Arctic atmospheric processes, especially where the tundra and ocean meet. 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…

Icy Arctic Proves Hot for Climate Data
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
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…

Partnerships Put the “Go” in the GoAmazon 2014/15 Campaign
Combining U.S. and Brazilian agencies and institutions and other international collaborators, the GoAmazon 2014/15 campaign will yield an unprecedented data set climate scientists can use to understand how aerosol and cloud life cycles in an unspoiled area are influenced by pollution emanating from a large tropical city.

First Use of ARM’s New FAA-Approved Arctic Airspace
A helicopter crew lowers rescue swimmer into the Arctic Ocean during a joint exercise with the Coast Guard and other private firms to assess using manned and unmanned aerial systems for search and rescue near Oliktok Point, Alaska. The test took place July 13, 2015, in DOE airspace recently approved for research by the FAA.…

Remote Region Promotes Remote-Control Science
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.
