Paper on forecast improvements due to dropsonde data from the Global Hawk aircraft published in Monthly Weather Review

Starting in 2010, the National Aeronautic and Space Administration and the National Oceanic and Atmospheric Administration have used the Global Hawk, an unmanned aircraft that can fly at 65,000 feet for 24 hours at a time, to make observations in tropical cyclones. The Global Hawk can release dropsondes that measure temperature, humidity, pressure, and wind […]
