Classified as one of the smallest and lightest Weather Radar available in the market!
Compact Dual Polarimatric X-band Doppler Weather Radar WR-2100

With ultra high definition spatiotemporal resolution capability, the WR-2100 Dual Polarimetric Doppler Weather Radar grasps omni-directional precipitation intensity in 50-metre-mesh in six-second-interval. By conducting high spatiotemporal resolution monitoring of the development process, three-dimensional structure as well as movement of a cumulonimbus, which causes precipitation, the development of short localised rainstorms can be predicted. Moreover, the WR-2100 has been downsized during the development phase to the extent that can be classified as one of the smallest and lightest Dual Polarimetric Doppler Weather Radar available in the market.

Example Setup

設置事例

A WR-2100 is installed at Rijeka University, in the Republic of Croatia, with the purpose of developing a prediction and early warning system for short, localised rainstorms. A mud flow/flash flood working group under SATREPS (Science and Technology Research Partnership for Sustainable Development) installed the WR-2100 as part of an action plan sponsored by the government of Japan.
Yosuke Yamashiki, Professor of GSAIS at Kyoto University, led a study group working on probability studies for sediment distasters using precipitation data from WR-2100. These studies concluded in March, 2014.

Features

Classified as one of the smallest and lightest Dual Polarimetric Doppler Weather Radar available in the market (Radome diameter: 108 cm, Radome weight: 68 kg)
Utilises solid state Radar technology
Solid state Radar technology reduces the operating cost thanks to the less power consumption as well as replacement of consumables. Moreover, high precision monitoring of precipitation is facilitated through a wide range of signal processing capability brought about by the solid state technology.
High-precision, real-time monitoring of precipitation intensity (mm/h)
Outputs moving velocity of nimbus
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
Suitable for localised meteorological monitoring as well as for monitoring of short localised rainstorm, when networked into “Multi-Radar System”

The antenna unit can be tucked in a minivan to be carried to the monitoring location. Also, it can be carried through an elevator to bring them up onto the monitoring site and installed by human personnel without using heavy machineries such as cranes.
