Adam Theisen: Managing ARM Instruments
Schooled in weather radars and quality control, one scientist leads ARM into a new era of data gathering This article continues a series of periodic profiles on scientists who create and apply ARM data. Atmospheric scientist Adam Theisen, a data quality expert with a background in radars, grew up on a 200-acre dairy farm in…

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…

MOSAiC PI Blog, Part 1: Frozen In and Facing the Arctic Head-On
Editor’s note: Matthew Shupe, co-coordinator for the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, sent back an update after the first leg. Season’s greetings. I’m sitting here, somewhat in purgatory, on the Kapitan Dranitsyn icebreaker heading back from MOSAiC Leg 1, and I wanted to write a brief summary to provide…

For the Arctic, an Epic Investigation
Embedded in sea ice for a year, a shipborne observatory will take a rare look at conditions in the rapidly evolving central Arctic More than 10 years after the idea was conceived, the largest research expedition to the central Arctic will commence September 20, 2019. Researchers will travel to the heart of the Earth’s northernmost…

Deciphering Cold-Air Outbreaks
A 2020 ARM field campaign in Norway will investigate critical but little-understood extrusions of cold air over warm waters In the northernmost reaches of Norway, within the Arctic Circle, a narrow island called Andøya points like a finger to the icy edge of the Arctic Sea 1,000 kilometers (620 miles) away. It’s surrounded by peat…

Decision Made on LASSO’s Next Case
A new type of case will soon join shallow convection in the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity. After more than a year sorting through possible expansion scenarios for LASSO, ARM leadership decided to make deep convection LASSO’s next focus. LASSO combines observations with LES modeling to get a more detailed…

Small Is Beautiful: Part 1
Researchers test instruments and record unique data by flying tethered balloon systems over the Southern Great Plains This is the first article in a series about small campaigns held in 2019 at ARM’s Southern Great Plains atmospheric observatory. Some field campaigns sponsored by the Atmospheric Radiation Measurement (ARM) user facility are called “small campaigns.” By…

Showcasing ARM’s Scientific Impact and Getting Feedback for ARM’s Future at 2019 AGU Meeting
“Celebrate the past and inspire the future”—the theme for the centennial meeting of the American Geophysical Union (AGU) was appropriate for how the Atmospheric Radiation Measurement (ARM) user facility showed up during this annual conference. With about 25,000 attendees, AGU is the largest international earth and space science meeting in the world. “ARM has been…
