The aim of our presentation is to introduce the preliminary steps of a new project. That is, a Hungarian UAV System, its on-board sensor setup, and the meteorological modelling background. Some preliminary results will also be presented. Our research applies atmospheric research measurements using Unmanned Aerial Vehicles supported by mesoscale meteorological model forecasts. The extensive research project was initiated in Hungary to develop the meteorological support of Unmanned Aerial Systems. The research programme includes (i) a statistical evaluation of the available historical data for aerodromes in the country, (ii) development of the forecasting methodology by numerical models and (iii) in situ measurements by Unmanned Aerial Vehicles using high sensitivity on board sensors for model evaluation and further analyses.
The UAV System we use is a multi-purpose Unmanned Aerial System (UAS) designed and built by the BHE Bonn Hungary Electronics Ltd. The main features of the aircraft are the following: 16 kg total weight, 3 kg maximum payload, electric propulsion, 60-90 km/h IAS cruising, approximately 60 minutes endurance. The aircraft is equipped with a two-way data communication system with a range of 15-20 km. A stabilized camera (visual and IR) can be part of the vehicle too. The aircraft can be piloted either by a remote operator or by an on board automatic robot control system. The on board flight computer stores a database that contains telemetric and flight information, airborne collected meteorological data and the time-stamped camera shots. The aircraft will be equipped with several meteorology sensors. The on board meteorology sensor data will be logged on board and transmitted in real time to the ground. A ground station will collect both the flight sensor data and the ground meteorology station data.
The planning of the survey program and the selection of sensors were based on the experiences from the SUMO (developed by the University of Bergen Geographical Institute) and the Mini-UAV M2AV (Universität Braunschweig, Germany) tests. The initial sensor setup includes the measurement of temperature, humidity, pressure, radiation, groundspeed, airspeed, orientation, and gravitational forces. In the near future, the purchase of radiation carbon dioxide and aerosol (PM10) sensors are planned. The laboratory test and calibration of a 5-hole probe, developed by the Technical University of Budapest has also been initiated. Application of this probe and a thermocouple sensor (for the fast detection of turbulence features) is the next planned step for the detection of momentum and sensible heat turbulent fluxes.
Test flights of the aerial meteorological measurements were started in 2012 fall. First steps were the detection of wind, temperature and humidity (Vaisala HMP45) vertical profiles in the lower 1-2 km layer of the Planetary Boundary Layer. In the flight planning procedure the numerical forecasts of the Weather Research and Forecasting Model (run by our Institute in order to yield meteorological support of this specific purpose) are also considered.
