Drones for Science: Long Range Fixed Wing UAVs New Tool in Understanding Climate Change

drones for scienceWeather 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 EUREC4A project (Elucidating the role of clouds-circulation coupling in climate), co-directed by the Max Planck Institute for Biophysical Chemistry in Hamburg (Germany) and the Dynamic Meteorology Laboratory (Laboratoire de Météorologie Dynamique: LMD) in Paris, brought more than 100 scientists from Europe and the United States to work on understanding climate issues.  “Understanding the effects of climate change on the tropical zone, and more particularly at the level of trade wind clouds, is a major challenge. Indeed, detecting property changes (even tiny ones) around these phenomena is essential as they illustrate the imbalances in heat exchanges that control the climate,” says a press release.  More than 10 international climate laboratories  with 5 oceanographic vessels, instrumented floats, land-based tools like balloons and aerosols, meteorological research aircraft, and drones  – including the BOREAL long range fixed wing participated to meet the challenge.

Drones for Science

Multiple drones were used during the project, with the BOREAL flying long range (over 100 km), in coordination with manned meteorological aircraft, “to collect measurements of radiometry, aerosols, temperature, humidity and turbulence in the lower layers of the atmosphere.”  Layers very close to the surface are poorly known because they are under-instrumented by scientists, even though they are precisely where the energy exchanges between the ocean and the atmosphere take place: but scientists lack data because it is too dangerous for manned aircraft to fly at an altitude of only 10 – 50 meters above the surface.
