Weather not only for rich man
Meteorological data from the WROC permanent station provided by Institute of Geodesy and Geoinformatics the Faculty of Environmental Engineering and Geodesy are now available on the web page of Wroclaw University of Environmental and Life Sciences.
The WROC station has been established on Prof. Stefan Cacoń’s initiative in November 1996. The station is presently managed under Prof. Jaroslaw Bosy guidance by researchers of Institute of Geodesy and Geoinformatics.
The main task of WROC Station is collecting permanently GNSS (GPS and GLONASS) satellite data and meteorological data, like temperature, pressure and relative humidity.
Originally the station was equipped with Ashtech Z–12 receiver and the Dorne Margolin ASH (ASH700936D_M) antenna installed on the roof of the building. However a clap of thunder damaged GPS antenna in July 1999. Therefore, in May 2000 the station was equipped with Ashtech Z–18 receiver with the Dorne Margolin ASH (ASH701941.1 SNOW) antenna. Meteorological data were acquired by using two meteorological sensors LAB EL and Olbrysz Ltd.
Since 13 April 2007, the WROC station has taken advantage of Leica GRX1200GGPRO receiver with LEIAT504GG LEIS antenna to continue observations of GPS/GLONASS satellites. The meteorological observations are realized using the meteorological station Paroscientific, Inc. MET4A, which was funded by the Head Office of Geodesy and Cartography in frame of ASG-EUPOS project.
Accuracy parameters of meteorological station:
- Pressure better than ±0.08 hPa from 500 to 1100 hPa,
- Temperature better than ±0.2 deg C from -50 to +60 deg C,
- Relative Humidity better than ±2 % from 0 to 100 %
The WROC station has worked within the confines of EUREF Permanent Network (EPN) in 1996 and to the International GNSS Service (IGS) in 2002. The WROC station has worked also within the confines of Active Geodetic Network ASG-EUPOS since 2008.
The GNSS satellite observations are collected with 1second data sampling interval, while meteorological data with 30 seconds. The observations are transferred on-line and in 1hour and 24hours blocks to the European Data Centers: Federal Agency for Cartography and Geodesy (BKG) in Frankfurt/Main and Space Research Institute, Department of Satellite Geodesy Austrian Academy of Sciences (OLG) in Graz and ASG-EUPOS management center in Warsaw.
The GNSS and meteorological observations realized by the station WROC are used in researches on Earth monitoring systems. Institute of Geodesy and Geoinformatics of Wroclaw University of Environmental and Life Sciences, which participates actively in this researches, realizes currently projects in the field of GNSS meteorology, remote sensing techniques and geodetic monitoring methods for geodynamics.
