An Arctic Sea Ice Surprise
Researchers find that more cracks in the ice lead to fewer—not more—low clouds Sea ice and low clouds interact offshore at ARM’s North Slope of Alaska atmospheric observatory. A recent study in Nature Communications revealed a counterintuitive link between “leads”―cracks in arctic sea ice―and the prevalence of low clouds during winter. Leads can be from…

ARM Seeks Lead Mentor for Ice-Nucleating Particle Analysis
The Atmospheric Radiation Measurement (ARM) user facility is seeking an instrument lead mentor (technical lead) for the collection and processing of aerosol filter samples to obtain distributions of ice-nucleating particles (INPs) at ARM observatories. ARM has supported the collection and analysis of aerosol particles to obtain INP number distributions on an as-requested basis for past…

Decision Made on LASSO’s Next Case
Deep convective clouds populate the night sky over Córdoba Province in Argentina. Such clouds will be the focus of a new case in the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity. Photo is by Jason Tomlinson, Pacific Northwest National Laboratory. A new type of case will soon join shallow convection in the…

DOE Labs Bolster Major ARM Effort in MOSAiC Expedition
In Tromsø, Norway, a multi-laboratory team from ARM and U.S. Department of Energy leadership gathered for the start of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The icebreaker R/V Polarstern (rear), transporting more than 50 ARM instruments, left Tromsø for the central Arctic on September 20, 2019. By the end…
