Vaisala Weather Radar WRM200
|
WRM200 is a dual polarization Doppler weather radar with already proven new applications like HydroClass" - 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.
Selection of applications such as:
weather surveillance
severe weather monitoring
hydrometeorological applications, e.g. flood forecasting
airport wind shear detection
hurricane/typhoon/cyclone tracking
