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 Measurement Research (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.

Pilot Phase Begins for Routine Large-Eddy Simulations
May 15, 2015       
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 of Energy (DOE) scientists, led by William [...]

Land, Sea, and Air: ACAPEX Targets Atmospheric Rivers
May 13, 2015       
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
Feb 25, 2015       
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
Feb 03, 2015       
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
Jan 23, 2015       
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 15 years—and aerosol-precipitation interactions.

Studying the Amazon Basin’s Climate by Air and by Land
Jan 15, 2015       
Scientists have now completed the first half of the interagency Green Ocean Amazon (GOAMAZON) campaign, a two-year study to determine how Mother Nature interacts with pollution from a city of 2 million people and the impact that interaction has on the pristine and delicate climate of Brazil’s Amazon Basin.

Seeing the Forest Through the Trees—And to the Aerosols
Jan 09, 2015       
Nine months in the icy, cold forests of Finland was not what the second ARM Mobile Facility (AMF2) was primarily created for, but because of its adaptability and reputation for stability in various climates and weather conditions, the AMF2 was essential for the Biogenic Aerosols - Effects on Clouds and Climate Campaign.

Around the World in 52 Months
Nov 14, 2014       
The Department of Energy has selected six field campaigns to take place from 2015 through most of 2019. These new efforts kick off in the summer of 2015 at the Southern Great Plains site and take the first ARM Mobile Facility from Brazil to Ascension Island, located in the southeast Atlantic Ocean between South America and Africa, in spring 2016.

Heartfelt Goodbye to Manus Island
Aug 27, 2014       
After 18 years, the U.S. Department of Energy’s ARM observation site at Manus Island is closed, but the data results will live on and remain available for use in the ARM Data Archive.
