“Change Is in the Air” as Scientists Evaluate Data Collection with Unmanned Aircraft
Mar 28, 2016       
For decades, studying Earth’s atmosphere meant gathering data with instruments based on land, lofted by balloons, or flown overhead in various types of aircraft, but change is "in the air" as increasingly popular unmanned aerial systems (UASs), such as lightweight miniature airplanes, prove useful for automating data collection. In April, the Evaluating Routine Atmospheric Sounding Measurements Using Unmanned Systems (ERASMUS) campaign will begin a second phase to collect a detailed data set and evaluate the potential for routinely collecting UAS data at the third Atmospheric Radiation Measurement (ARM) Mobile Facility at Oliktok Point, Alaska.

ASR Atmospheric Convection Workshop Held
Mar 28, 2016       
Atmospheric moist convection is a primary process through which much of the heat from the surface of the Earth is transported to the upper troposphere. This process starts out with the formation of small shallow clouds that rise from the boundary layer, which under the right environmental conditions grow into deep thunderstorms that produce rain. These [...]
