In the Air and on the Ground, an Azores Search for Better Data
Updated February 19, 2018: The Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign is coming to a close the week of February 19, 2018. Here is the initial feature article on ACE-ENA from May 2017. In a coming campaign, weeks of interlocking observations on marine clouds and aerosols During the ACE-ENA…

From STORMVEX, Novel and Deep Correlative Data Sets on Cloud Properties
Linking radiosondes, planes, and mountainside instruments to study winter clouds It is rarely a good idea to tell a scientist she has her head in the clouds. But Anna Gannet Hallar, an atmospheric scientist who specializes in aerosol and cloud microphysics, thinks that is a lovely idea. ARM Facility Manager Nicki Hickmon cleans the lens…

At Brookhaven, ‘Wide-Eyed’ Visitor Takes in American Science and Culture
Maris Palo is pictured at her university laboratory in Tartu, Estonia. In her native Estonia, budding atmospheric scientist Maris Palo is a doctoral student at the University of Tartu. When she is not cracking books or watching over instruments in the field, she works at the university’s Laboratory of Environmental Physics. Her academic specialty is…

ARM Successfully Completes Challenging Antarctic Atmospheric Study
First sophisticated Antarctic cloud, aerosol data collected to improve earth system models for the region Melting sea ice appears on McMurdo Sound, West Antarctica, where ARM deployed sophisticated climate instruments to capture rare data. In a science campaign of unprecedented challenge, researchers recently completed the first substantial climate measurements on the West Antarctic Ice Sheet in…

Spanning, Scanning the Skies with Data-Scooping ARM-ACME
A look at the late, great campaign for measuring mid-continent greenhouse gases More than a decade of air samples came from over the Southern Great Plains atmospheric observatory. One day in March 2000, a Cessna 172 took off from a little airstrip in Ponca City, Oklahoma. The intent: Measure air samples of dried aerosol particles…

Capturing Clouds for LASSO Leads to New Radar Techniques
Modelers and measurers work together to improve cloud measurements The ARM Climate Research Facility has some of the best instruments in the world for measuring atmospheric properties, but achieving the highest-quality results requires knowing the optimal way to use them. In a recent paper, a research team used ARM data to optimize radar measurements and…

HI-SCALE Finishes Collecting Data About Shallow Convective Clouds
ARM field campaign gathers data that will be used to examine the life cycle of shallow convective clouds What controls the initiation, maintenance, and distribution of shallow convective clouds? The just-finished ARM campaign Holistic Interactions of Shallow Clouds, Aerosols, and Land-Ecosystems, or HI-SCALE, collected data that will help answer that question. Making use of ARM’s…
