The designation TAWES stands for partially automatic weather recording system . This can be equated with the meteorological measuring network of all state weather stations in Austria.

history

There have been numerous meteorological measuring stations since ZAMG was founded and even before that. One of the first is the weather station of the Kremsmünster observatory , whose records go back to 1763. In the further course the existing measuring network was repeatedly equipped with modern technology. It was only a matter of recordings and their archiving; there was still a long way to go before the data could be used for Austria-wide weather forecasts. Until well into the twentieth century, the weather conditions at the stations were read off on the main meteorological dates (0, 6, 12 and 18 UTC ) and sent by post to Hohe Warte.

It was only with the advent of the Internet that it became possible for the first time to automatically transmit weather data to a control center.

The first expansion stage of the Austrian weather station network started in 1992 with the support of the BMWF . At that time there were 71 state weather stations in Austria, of which a total of 62 TAWES stations were connected to the Internet and transmitted all weather values ​​every 10 minutes. The planned expansion phase of the TAWES network comprised 120 stations.

However, this was only the first of several expansion stages of the weather station network in Austria. Today, after further expansion phases in the past decades, the TAWES network comprises 250 measuring points throughout Austria, with weather stations operated by third parties (such as at airports by Austrocontrol or partner weather stations of Ö3 ) there are even 266.

Furthermore, 130 phenology stations are also integrated in this measurement network.

Measurement and properties

All weather stations and measuring devices in this network comply with the international WMO certification . Among other things, the following meteorological parameters are recorded every moment and transmitted to the data processing center in Vienna every 10 minutes: air temperature , humidity (and the resulting dew point ), precipitation and amount of precipitation , air pressure , global radiation , wind direction and wind speed at a height of 10 meters above ground, ground temperature in 5 cm high and 3 temperatures in different soil depths.

Most of the stations are semi-automatic because some parameters such as type of cloudiness and the like can only be perceived and recorded by a weather observer. These records are recorded and evaluated in so-called climate sheets.
