Features

Dual Polarization

High precision rain observation & accurate measurements

The Dual Polarization of the WR2120 recovers signal intensity loss and attenuation caused by heavy rain.

Particle classification

Several data such as echo strength or phase difference, provided by the WR2120, can be utilized to assess the nature of the detected particle and deduct whether it is Snow, Hail or Rain.

Easy installation

Very compact and lightweight (ø1m, 65 kg)
No heavy equipment required for installation
Compatible with regular power outlet

Reduced operating costs

Solid-State
- Reliable, less maintenance, long life solid-state transmission device
- Low power consumption（100V, 200W）

High resolution & accurate measurements

Outputs dual polarimetric Doppler information (Zdr, Kdp) for computing diameter of precipitation particles as well as discriminating types of precipitation (rain, snow, etc.)
3D scan to observe the vertical structure of a cumulonimbus

Various software applications available
