Climatological weather observations serve long-term scientific purposes and provide important  data input for sophisticated weather models and climate change research.  A key requirement for climatological observation systems is to provide continuous,  homogenous and high quality measurement data over a long time period.

The most commonly measured parameters are air temperature, precipitation, humidity, wind speed and direction, and atmospheric pressure. Meeting the requirements of high quality and accuracy requirements of climate monitoring starts already at the measurement site. Vaisala HydroMet™ Automatic Weather Stations with its precise and reliable sensors will produce high quality measurement data for your needs.
