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.

Up, Up, and Away!
This summer, researchers are launching an unprecedented number of weather balloons in rural Oklahoma to collect data to help improve how weather and climate models predict the diurnal cycle of rainfall and cloud development.

North to Alaska: Researchers Rush to Understand Warming Trend
ARM-ACME V field campaign makes first science flight June 4 ARM-ACME V researchers are studying populations of liquid droplets and ice crystals in clouds such these seen above the arctic tundra at the ARM Facility at Oliktok Point. A group of scientists from the Atmospheric Radiation Measurement (ARM) Climate Research Facility won’t be looking for…

Sleepless on the Great Plains
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…

Pilot Phase Begins for Routine Large-Eddy Simulations
William Gustafson, Pacific Northwest National Laboratory Researchers target observation and modeling together for a new level of scientific analysis on climate When it comes to clouds, the Earth’s energy budget, and tiny aerosols, scientists don’t have all the answers. However, each atmospheric model improvement brings them a small step closer. A team of U.S. Department…

Land, Sea, and Air: ACAPEX Targets Atmospheric Rivers
After six weeks of gathering data from air and sea in California, scientists are back on dry land ready to examine their findings. The team, led by Ruby Leung at Pacific Northwest National Laboratory, chased and sampled a total of four atmospheric rivers that made landfall in northern California during ARM Cloud Precipitation Experiment (ACAPEX).

Nature Article: Carbon Dioxide’s Greenhouse Effect at Earth’s Surface Confirmed Using ARM Data
Scientists have for the first time observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface. The research, conducted using data and data products from the Atmospheric Radiation Measurement (ARM) Climate Research Facility, is reported Wednesday, February 25, in the advance online publication of the journal Nature.

North Slope Megasite Preparations Take Form
This fall, the installation of the third ARM Mobile Facility was completed at Oliktok Point, Alaska, with the addition of scanning and vertical-pointing radars, as well as a Raman lidar. With 4 years remaining as planned in the extended deployment at Oliktok, the first year of data collections was completed on September 30, 2014.

Chasing Aerosols and Atmospheric Rivers
Over the next six weeks during the ARM Cloud Aerosol Precipitation Experiment, DOE’s second ARM mobile facility and ARM Aerial Facility will be collecting data to improve computer models that predict extreme events in a changing climate. Researchers are hoping to find more answers to atmospheric rivers—a phenomenon only identified by scientists in the last…
