The ARM West Antarctic Radiation Experiment (AWARE) is a long-overdue effort to collect fundamental data in a challenging and remote region where changes in climate have worldwide implications. AWARE principal investigators from Scripps Institution of Oceanography at UC San Diego and Brookhaven National Laboratory, and the Atmospheric Radiation Measurement (ARM) Climate Research Facility technical director, will discuss the field campaign, which launched in November, at a special workshop at the AGU Fall Meeting: 5 p.m. Wednesday, Dec. 16 at the Fall Meeting Press Conference Room (Room 3000, Moscone West).
Scientists uncover secrets behind hurricanes, monsoons, and polar vortexes.
