“Change Is in the Air” as Scientists Evaluate Data Collection with Unmanned Aircraft
Mar 28, 2016       
For decades, studying Earth’s atmosphere meant gathering data with instruments based on land, lofted by balloons, or flown overhead in various types of aircraft, but change is "in the air" as increasingly popular unmanned aerial systems (UASs), such as lightweight miniature airplanes, prove useful for automating data collection. In April, the Evaluating Routine Atmospheric Sounding Measurements Using Unmanned Systems (ERASMUS) campaign will begin a second phase to collect a detailed data set and evaluate the potential for routinely collecting UAS data at the third Atmospheric Radiation Measurement (ARM) Mobile Facility at Oliktok Point, Alaska.

Tracking Clouds Down Under
Feb 29, 2016       
While penguins and seals are the main inhabitants of Macquarie Island, a remote grassy outcrop which lies about half-way between New Zealand and Antarctica, they will soon be joined by a suite of instruments from the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility. These instruments will measure surface radiative fluxes and cloud and aerosol properties at this locale for two years, providing vital information for climate scientists and meteorologists.

MAGIC Continues to Inspire Insights
Feb 08, 2016       
Because they cover so much of the Earth and reflect large amounts of sunlight, marine clouds play an especially critical role in climate and climate research. However, most non-satellite investigations of such clouds have been relatively short-term (~one month) in fairly small regions. The Marine ARM GPCI Investigation of Clouds (MAGIC) field campaign changed that by placing the second ARM Mobile Facility on the Horizon Spirit in 2012 and 2013.

Scientists Study Clouds’ Impact on West Antarctic Ice Melt
Jan 19, 2016       
It has been half a century since the West Antarctic atmosphere has been studied in detail and an “unprecedented deployment” of instruments from the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility is now delivering data that could help scientists understand how clouds affect melting glaciers.

Scientists Find Mostly Liquid Particulates over Amazon Rainforest
Dec 07, 2015       
When scientists participating in the GoAmazon 2014/2015 experiment measured the physical state of aerosols drifting over the Amazon rain forest, they found that 80 percent of the time those particles were liquid. Their findings, published in Nature Geoscience December 7, were a surprising departure from the results of a previous study.

Covering All Bases: Probing the Spectrum of Land-Atmosphere Interactions
Dec 07, 2015       
ARM-funded experiment to determine the flow of heat and moisture between Earth and air In less than a year, mile-long fiber optic cables will stretch across prairies and crop fields in Oklahoma, allowing scientists to gain the clearest picture yet of the exchange of heat and moisture between the land and the atmosphere. By determining these [...]

MC3E: A Legacy of Learning
Dec 07, 2015       
Four years after the field research campaign ended, data are yielding the secrets of storms Large storm clouds influence the Earth's climate system by redistributing heat and moisture in the atmosphere and delivering rain to the surface, yet current climate models struggle to accurately reproduce storm systems. To help resolve this issue, the U.S. Department of [...]
