Revisiting Antarctica’s AWARE
Concerns today spark reflections on an ARM campaign whose data from West Antarctica remain uniquely useful eight years later Given Antarctica’s extreme conditions, including winds spiking to 200 miles per hour, it is hard for atmospheric research stations to collect data there. This ARM mobile observatory operated during the 2015–2017 ARM West Antarctic Radiation Experiment…

An ARM View of AGU23
In the maelstrom of a 5-day international conference, DOE and ARM find ways to shine Visitors flock to the ARM booth during the 2023 American Geophysical Union (AGU) Fall Meeting in San Francisco, California. If “Seinfeld” is a show about nothing, the annual fall conference of the American Geophysical Union (AGU) is a show about…

A Decade of GoAmazon
Ten years later, campaign data gathered in Brazil by ARM and international collaborators have proved highly influential across atmospheric science The Amazon rainforest contains billions of trees, leading to its characterization as a green ocean. A decade ago, ARM participated in the multi-institutional Green Ocean Amazon (GoAmazon2014/15) field campaign. GoAmazon data have informed more than…

Science Workshop Outlines a TRACER Future
Researchers gather in Texas and online to share data, preliminary results, collaborations, and next steps from the Houston-focused ARM campaign Houston, Texas, is a city of storms that attracted researchers of deep convection with its mix of aerosol influences from industry, rural landscapes, and sea breezes. Photo is by Guy Tubbs. To gain the most…

MOSAiC Data Reveal Arctic Seasonal Atmospheric Processes
Direct observations reported in new Nature Communications paper The following is based on a story by Anne Manning, Colorado State University. Jessie Creamean, a research scientist at Colorado State University, collected samples of air, seawater, sea ice, and snow in the central Arctic during the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate…

ARM Data Show Potential of Forests to Affect a Continent’s Climate
In a Scots pine forest, ARM’s Aerosol Observing System collected data during the 2014 Biogenic Aerosols – Effects on Clouds and Climate (BAECC) field campaign in Hyytiälä, Finland. In Scandinavia and other northern lands, boreal forests produce gases that contribute to particle formation. In the atmosphere, these particles can influence cloud properties and, by extension,…

Understanding Low Clouds in a Remote Marine Environment
After just a few years, an ARM campaign in the cloud-decked Azores spins off prolific research on aerosol effects ARM’s Eastern North Atlantic (ENA) atmospheric observatory sits in a prime location for studying low marine clouds. The Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign in 2017 and 2018 combined aircraft…

Storm Chasers, Knowledge Makers
Recent work spanning two related field campaigns in Argentina gets play in the same journal The 2018–2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign used an ARM aircraft, pictured, to collect data on properties of clouds and aerosols over Argentina’s Sierras de Córdoba mountain range.

From COMBLE, a Boom of Big Plans
A data-rich study of cloud evolution in the Norwegian Sea marine boundary layer is the focus of multiple modeling efforts In this satellite image from high over the Norwegian Sea on March 28, 2020, a cold-air outbreak spurs the formation of “cloud streets.” As these broken cloud decks stream southward, they evolve into cellular patterns.…
