Counting Down to the Launch of Mega-Campaign MOSAiC
Editor’s note: Anjeli Doty of the Los Alamos National Laboratory ARM team sent in this update. Matthew Shupe, MOSAiC’s co-coordinating scientist, discusses how ARM’s ICERAD radiometer suite will measure downwelling shortwave (visible light) and longwave (infrared) radiation during the campaign. In 2008, Shupe studied coupled ice, atmospheric, and ocean systems for six weeks at the…
