Doppler radar to boost weather forecasting [Agriculture]
n a bid to improve weather forecasting services, Indian Space Research Organisation has commissioned a Doppler weather radar at the Vikram Sarabhai Space Centre (VSSC).
The C- band Polarimetric Doppler weather radar (C-DWR) is the fi rst of its kind in South India.
The data generated by the DWR would be shared with the India Meteorological Department to supplement its prediction.
The only other C- DWR in the country is at Chirapunji. Two more units are coming up at Bhuj in Gujarat and Gopalpur in Odisha.
The DWR is expected to aid rainfall estimation and detect thunderstorm, cyclones and other severe weather events within a radius of 400 km.
It has instruments to measure rainfall intensity, wind shear and velocity and locate a storm centre and the direction of a tornado or gust front.
The radar is designed to improve precision in long range weather forecasting and surveillance using the Doppler effect. It works by bouncing a microwave signal off a target and analysing how the object’s motion has altered the frequency of the return signal.
