Weather researchers are discovering the value of using drones for science. In a project designed to help understand current climate issues used the BOREAL fixed-wing UAV equipped with specialized sensors to gather data from areas around Barbados. The project brought more than 100 scientists from Europe and the United States to work on understanding climate issues. Our interest is in the equipment used, but for the record - the project is called EUREC4A - also known as Elucidating the role of clouds-circulation coupling in climate.
