Thirteen scientists from Germany, France and the United States collaborated to collect measurements and process them into a dataset that provides a rich characterization of the thermodynamic and kinematic aspects of the atmosphere in the North Atlantic trades. The effort was led by Dr. Geet George, a post-doctoral scientist at the Max Planck Institute for Meteorology, who was also responsible for the dropsonde operations aboard the HALO aircraft during the EUREC4A field campaign in 2020.
A dropsonde is a device dropped from aircraft to obtain a vertical profile, or “sounding”, of atmospheric properties. It measures location using global navigation systems (such as GPS), from which it derives the wind speed and direction while measuring temperature, pressure and humidity. It can be used to collect in-situ data from remote regions and to understand atmospheric processes and changes.
