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. A simulation shows clouds from the May 20, 2011, mesoscale convective system as it passes over ARM’s Southern Great Plains atmospheric observatory in Oklahoma. The simulation used the Weather Research and Forecasting model…

Saudades for the Azores
Francesca Gallo, Los Alamos National Laboratory Francesca Gallo, an atmospheric scientist at Los Alamos National Laboratory, sent in this post. I first arrived in the Azores on a foggy, wintery January day. I remember only clouds and cows everywhere. “It’s just for six months, not a day more than that,” I thought. Almost seven years…

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…

Gearing Up for a Stormy CACTI Deployment
Editor’s note: Anjeli Doty of the Los Alamos National Laboratory ARM team sent in this update. Anjeli Doty, Los Alamos National Laboratory Towering stacks of ominous dark clouds, splitting strikes of bright lightning, and torrential rain typify weather in the rugged Sierras de Córdoba mountain range in north-central Argentina. It is a place to find…

Eclipse’s Shadow Felt on Southern Great Plains Instruments
While the total solar eclipse of August 21, 2017, wowed spectators throughout the United States, instruments at the ARM Facility’s Southern Great Plains (SGP) atmospheric observatory recorded data connected to the rare event. The first total solar eclipse to sweep across the United States in 99 years appeared as a partial eclipse over the SGP,…
