Buoyed by a sense of adventure and a passion for clouds, a scientist studies the fragile Arctic and plans a shipborne field campaign adrift for a year in sea ice This is the 11th article in a series of profiles on members of the ARM User Executive Committee (UEC). Matthew Shupe brings his passion for…

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 brings cloud-research radar expertise to ARM’s User Executive Committee. Pavlos Kollias…

One scientist, inspired early by world travel and the power of tropical storms, uses radar to investigate how large convective systems organize This is the ninth article in a series of profiles on members of the ARM User Executive Committee (UEC).  Courtney Schumacher brings her wide-ranging radar expertise to ARM’s User Executive Committee, along with…

Two University of Arizona researchers solve an old puzzle about the prevalence of rain and agricultural activity A summer storm begins to gather at the Southern Great Plains atmospheric observatory, where farm and ranchland coexist with instrumentation. A new paper, based on research funded by the National Aeronautics and Space Administration (NASA), strongly demonstrates “the…

A 2011 field campaign on convective clouds has so far yielded 57 papers and some transformative science MC3E ARM leadership pose in the field, from left to right: Scott Giangrande, BNL;  Michael Jensen, BNL; Pavlos Kollias, BNL and Stony Brook University; and Nitin Bharadwaj, Pacific Northwest National Laboratory. MC3E, or the Midlatitude Continental Convective Clouds…

Outside campaigns and agencies routinely sample the atmosphere above ARM observatories From the air over Ascension Island in the Azores, instruments await packing after the Layered Atlantic Smoke Interactions with Clouds (LASIC) field campaign. During LASIC, many collaborative overflights by NASA aircraft took place in 2016 and 2017. On March 10, researchers from the United…

Hooked on science early, researcher and professor Gannet Hallar now investigates clouds and aerosols in the Intermountain West This is the eighth article in a series of profiles on members of the ARM User Executive Committee (UEC). Gannet Hallar brings university connections to ARM’s User Executive Committee. In the summer of 1998, Gannet Hallar was…

Pursuing the best way to merge regional and global models keeps Erika Roesler rapt and running This is the seventh article in a series of profiles on members of the ARM User Executive Committee (UEC). Erika Roesler is the UEC’s designated “young investigator” representative. As an undergraduate studying physics and astronomy at Northern Arizona University,…

A ready-made structure and other gear will restore lost datastreams In late June 2018, workers prepare the Cape San Juan data-collection observatory in the shadow of a historic lighthouse. A pair of foundation columns will support two instrument containers. All photos are courtesy of John Ogren (retired from NOAA). Last year, just after 6 in…
