METEOROLOGICAL DATA ANALYSIS OF THE TUBO PERMANENT GNSS STATION Michal Vojkůvka, Jiří Bureš Brno University of Technology Faculty of Civil Engineering

TUBO – Description 1 – TUBO GNSS station 2 – GNSS calibration baseline 3 – Meteo (T, P, e%) 4 – Meteo (wind, precipitation) 5 – Meteo (solar radiation)

Solar radiation Wind speed & direction Air temperature, relative humidity, static pressure Precipitation

Solar radiation

Laser Precipitation Monitor Amount as water equivalent Precipitation type Size Velocity Intensity Radar reflexivity Z Visibility MOR

Data Analysis Data drop-out (measurement system failure) Measurement system subpart failure Sensor replacement Measurement system subpart recalibration Time-shift of the measurement system subparts Other random effects

Technologies Used Firebird database engine – based on Borland InterBase 6.0 source code, open source ASP – server side dynamic HTML, JavaScript – client side
