Weather drone

A weather drone, or weather-sensing uncrewed aerial vehicle (UAV), is a remotely piloted aircraft weighing less than 25 kg and carrying sensors that collect thermodynamic and kinematic data from the mid and lower atmosphere (e.g. up to 6 km).

Weather drones are not yet used to support National Meteorological and Hydrological Services (NMHS) due to ongoing negotiations on UAVs' access to airspace and compliance with airspace regulations and technological development needed to meet the World Meteorological Organization's requirements.

Mostly, weather drones are deployed to support scientific research missions and industry-specific operations.
