Vaisala Weather Radar WRM200


The WRM200 is a dual polarization Doppler weather radar with already proven new applications like HydroClass™ - the real time operational hydrometeor classification software. This software is the first COTS product that uses real-time polarization measurement for classifying targets into categories such as hail, snow pellets, snow or rain. The WRM200 provides superior data quality, accurate measurement, easy maintenance access, low maintenance costs, semi-yoke style antenna/pedestal with a low momentum of inertia and weight.

A selection of applications:

  • weather surveillance
  • severe weather monitoring
  • hydrometeorological applications, e.g. flood forecasting
  • airport wind shear detection
  • hurricane/typhoon/cyclone tracking
