Capturing Clouds for LASSO Leads to New Radar Techniques
Nov 21, 2016       
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 accompanying [...]

HI-SCALE Finishes Collecting Data About Shallow Convective Clouds
Oct 17, 2016       
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 Southern [...]

Capture, Send, Check, Store: ARM’s Continuous Flow of Climate Data
Sep 19, 2016       
From instruments to archives, terabytes on Sun, Clouds, Wind, and Gases In the sky over the Azores, in the remote Atlantic Ocean, a bank of clouds dips toward a radar on Graciosa Island. Data point. In Oliktok, Alaska, arctic sleet patters against a sensor. Data point. Near a wheat field in flat central Oklahoma, an airborne particle falls [...]

ARM Data Flow: A Look Back
Sep 19, 2016       
From its inception in 1990, the Atmospheric Radiation Measurement (ARM) Climate Research Facility has focused on four topics: science, instruments, sites, and data. Over time, the science focus evolved, expanding from radiative transfer to atmospheric processes and then to improved parameterizations for models. Instruments got more robust and numerous. The number of sites grew; ARM added [...]

ARM Principal Investigator Quoted in Science
Sep 19, 2016       
LASIC principal investigator was quoted in a Science news story about African smoke and ocean clouds. Science magazine quoted Paquita Zuidema, University of Miami, in her role as lead scientist for ARM’s Layered Atlantic Smoke Interactions with Clouds (LASIC) campaign. Published August 25, “NASA Aircraft Probe Namibian Clouds to Solve Global Warming Puzzle” describes how NASA’s [...]

Spying on Thin Ice Clouds
Aug 15, 2016       
Observations of thin ice clouds are scarce, contributing to a large range of uncertainties in present-day and future simulations of the polar climates. Data from the Thin Ice Clouds in Far Infrared Experiment, or TICFIRE, and ARM's Barrow facility will help to develop a new spaced-based instrument in collaboration with the Canadian Space Agency to measure these thin ice clouds.

Reconfiguring ARM: Arctic Eyes in the Sky
Jul 18, 2016       
The Inaugural Campaigns for ARM Research using Unmanned Systems—or ICARUS—is underway at Oliktok Point, Alaska. In response to researcher input, ICARUS was developed as the Atmospheric Radiation Measurement (ARM) Climate Research Facility's first initiative to begin routine operations using unmanned aerial systems (UAS) and tethered balloon systems (TBS) to collect spatial information about the rapidly changing arctic environment.

In India, a Science Journal Celebrates Insights from a Ganges Valley Climate Study
Jul 18, 2016       
ARM instrumentation played a big role in the first joint U.S.-Indian experiment of its kind The Ganges River begins in a narrow valley in the Himalayas and flows eastward through a vast valley of farms, cities, power plants, and factories before exiting mightily into the Bay of Bengal. The 2,500-kilometer waterway, fed by Himalayan runoff and [...]

Caring for CARES: A California Air Study Keeps Spinning a Web of Research
Jun 20, 2016       
During June of 2010, a lot of people cared about the Carbonaceous Aerosols and Radiative Effects Study (CARES), a 26-day investigation of the composition, evolution, and fate of aerosols in an air transport region where both natural and urban emissions mix.

BAMS Article Reports on a Data-Rich ARM/NASA Storm Clouds Campaign
Jun 20, 2016       
Midlatitude Continental Convective Clouds Experiment to be published in upcoming edition Convective clouds distribute water, heat, and momentum throughout the lowest layer of the Earth’s atmosphere, where weather happens. They get their name from the convective motion prompted when the surface of the Earth heats up, causing air to become buoyant and rise into the atmosphere. With [...]
