Paper on the impact of dropwindsondes from the Global Hawk on forecasts published in Monthly Weather Review

Summary:  A drone, what we call an unmanned aircraft system, can collect data in tropical cyclones (TCs) to improve forecasts.  Scientists have used the Global Hawk drone that can fly at an altitude of up to 60,000 feet for over 24 hours at a time since 2010. The Global Hawk releases dropwindsondes that measure wind, … Continue reading Paper on the impact of dropwindsondes from the Global Hawk on forecasts published in Monthly Weather Review
