MOSAiC PI Blog, Part 3: Science in Polar Night
Editor’s note: In the central Arctic, the sun will soon rise above the horizon, ending the monthslong “polar night” over the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Matthew Shupe, MOSAiC co-coordinator from the University of Colorado, Boulder, shares some of his MOSAiC photos taken during polar night. ARM technician Juarez…

CACTI Deep Convection Chosen for Next LASSO Scenario
Editor’s note: William Gustafson, principal investigator for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity, sent in this update. Deep convection during the CACTI field campaign was complex, and it exhibited some of the tallest clouds ever measured by ARM. Photo is by Jason Tomlinson, Pacific Northwest National Laboratory. I am excited…

MOSAiC Blog: Sights of the Arctic, Part 2
Editor’s note: David Chu, operations manager for the second ARM Mobile Facility, recently returned from the first leg of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Below are several MOSAiC photos taken by Chu, of Los Alamos National Laboratory. Our first day in the ice, we took an ARM MOSAiC install…

MOSAiC Blog: Moving Over to the ‘Dark Site’ of the MOSAiC Floe
Typically what I look like after a day outside coring for ice. This day was particularly cold … almost minus 45 degrees Celsius (minus 49 degrees Fahrenheit) with the wind chill. It can be so cold that your breath instantly turns to ice on your face. Eyelashes are great collectors of moisture turned into ice…

Proposed LASSO Expansion Scenarios Get a Deeper Look at Workshop
Editor’s note: William Gustafson, principal investigator for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) workflow, sent in this update. The LASSO team is considering possible scenarios to expand the workflow beyond shallow convection at ARM’s Southern Great Plains atmospheric observatory. A workshop earlier this year helped us move closer to making a…

Closing Out the Ice Formation Closure Study
Editor’s note: Daniel Knopf is the principal investigator (PI) of the Aerosol-Ice Formation Closure Pilot Study (AEROICESTUDY). It is the first attempted study of its kind at ARM’s Southern Great Plains (SGP) atmospheric observatory. Knopf, a professor in the School of Marine and Atmospheric Sciences at Stony Brook University in New York, sent in this…
