Journal Nods to CACTI
Some of the world’s most destructive thunderstorms crop up in Argentina, along the eastern side of the Andes. The journal Nature recently highlighted current research efforts, including an Atmospheric Radiation Measurement (ARM) user facility field campaign, to improve understanding of these storms. The Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign began in October…

Share Your Ideas on Growing LASSO Part 4: Continental Deep Convection
Editor’s note: William Gustafson, principal investigator for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) workflow, sent in this update. I get asked one question over and over again, ever since beginning the LASSO project. “When is LASSO going to do deep convection?” Sometimes the person asking is just playing with me to…

UEC Profile: ‘An ARM Loyalist’
As a graduate student, Pavlos Kollias discovered the allure of millimeter cloud radar, a specialty that he says put him ‘among great minds’ This is the 10th article in a series of profiles on members of the ARM User Executive Committee (UEC). Pavlos Kollias says most people think of radars as sensors that monitor and…

How to Fit a Planet Inside a Computer: Developing the Energy Exascale Earth System Model
The Earth was apparently losing water. L. Ruby Leung, a scientist from the U.S. Department of Energy’s (DOE) Pacific Northwest National Laboratory in Washington state, and her team were baffled by their results. “We were seeing the sea level decreasing at an alarming rate.” Fortunately, Leung and her team were only looking at a virtual Earth.…

Share Your Ideas on Growing LASSO Part 2: An Eastern North Atlantic Option
Editor’s note: William Gustafson, principal investigator for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) workflow, sent in this update. In June 2018, I shared our plan for a series of blog entries on expansion options we are considering for the LASSO workflow. While we will continue to conduct simulations of shallow convection…

For Storm-Wracked Science in Puerto Rico, ARM Steps Up
A ready-made structure and other gear will restore lost datastreams Last year, just after 6 in the morning on September 20, Hurricane Maria first hit land in Puerto Rico, packing 115 mph winds and heavy rain. The storm slashed across the island from south to north like a buzz saw, knocking out power lines, roads,…
