Meteodrone data

The University of Nebraska-Lincoln (UNL) Meteodrone (model SSE MM-641) is a small (1.1 kg GTOW, ~40 cm across) hexcopter UAS manufactured by Meteomatics. Maximum endurance is approximately 30 min and estimated maximum operating altitude of 1500 m. Profiles can be executed at ascent/descent rates up to 10 m/s. The Meteodrone is capable of measuring temperature, relative humidity, wind velocity and GPS position time-stamped with GPS time. Temperature and dual relative humidity sensors are shielded from solar exposure by a housing with a vertically oriented air intake and hoirizontal exhaust. Sensor aspiration is driven by rotorwash across the horizontal exhaust. In its current configuration data are recorded only when executing vertical profiles. Attitude and position are updated at a data rate of 20 Hz while meteorological observations are updated at 10 Hz.
