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…

Studying the Amazon Basin’s Climate by Air and by Land
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
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.
