• IMD plans to replace all the existing old generation radars with state-of-art S-Band DWRs in a phased manner.
• IMD has already installed 4 nos. S-Band imported DWRs at Chennai(2002), Kolkata(2003), Machilipatnam (2004) & Visakhapatnam(2006) replacing the old generation S-Band cyclone detection radars at these places.
• IMD has also installed one indigenous Doppler Weather Radar at Sriharikota (AP) in 2004, it was developed under MoU with ISRO Bangalore.
• India Meteorological Department has a plan to install 2 more indigenous S-Band DWRs at Bhuj and Kochi to be developed by M/s BEL, Bangalore.
• Under First Phase of modernisation, IMD also has a plan to replace old S?Band Cyclone detection Radar by S Band Doppler Weather Radar at 12 locations namely Mumbai, Paradip, Nagpur, Patna, Lucknow, Patiala, Karaikal, Bhopal, Agartala, Mohanbari, Delhi and Goa.
