## ANSWER

## THE MINISTER OF EARTH SCIENCES (SHRI KIREN RIJIJU)

- (a) Currently, there are 39 Doppler Weather Radars (DWRs) installed at various locations and are well distributed across the country. The details are provided in Annexure-I. Currently, there is no radar in the North Karnataka and Jharkhand.  The procurement of  DWRs  to  be  installed  at  Mangalore  and  Bangalore  in  the  State  of  Karnataka; Ranchi in Jharkhand and Aurangabad in Maharashtra has been initiated.
- (b)-(c)  The C-Band Radar has a greater range (250 km) than the X-Band Radar (100 km) due to  its  better  propagation  characteristics. The C-Band Radar antennas are larger than the X-Band Radar antennas, so they usually demand a higher investment.
- (d)-(e)  The  locations  of  these  DWRs  have  been  distributed  in  the  best  possible  way  to monitor severe weather conditions across multiple States of the Indian region. Some of  the  regions  are  not  covered  by  the  present  network  and  hence  steps  have  been initiated for  procurement of additional 12 C-Band  DWRs  to  be  installed at Aurangabad,  Port  Blair,  Ranchi,  Ahmedabad,  Mangalore,  Balasore,  Malda,  Agatti, Bangalore, Sambalpur, Raipur, Aaloand 16 X-Band DWRs to be installed in North East region at Guwahati, Jorhat, Tezpur, Silchar, Imphal, Aizawl, Dimapur, Dhubri, Seppa, Miao and urban regions of Pune, Varanasi, Kolkata, Kozhikode, Bhubaneswar and Purnea.
