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.

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.

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…

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…
