- IMD
adopted radar technology for meteorological applications in the
early fifties.The
first indigenously designed and manufactured X-band storm detection
radar was installed in 1970 at New Delhi.
- An
integrated upper air sounding system comprising X-Band weather-cum-windfinding
MULTIMET radar and radiosonde system (401 MHz), designed and
produced indigenously, was introduced in IMD in 1975.
- The first
S-band cyclone detection radar became operational at Visakhapatnam
in 1970. The first Indian made S-band cyclone detection radar was
commissioned at Mumbai in 1980.
- IMD now has
a network of 10 S-band cyclone detection radars covering the Indian
coast-line.
- IMD's
operational network of X-band radars consists of 9 wind-finding
radars, 9 storm detection radars and 8 radars with dual capability.
- Ten X-band
radars, which had outlived their lives, were replaced by digital
X-band radars in 1996.
- IMD plans to
replace the existing cyclone detection radars with state-of-art
Doppler Weather Radars in a phased manner. The first two radars to
be replaced in 2001 by Doppler Weather Radars will be those at
Calcutta and Chennai.
- An
indigenous Doppler weather radar is being developed under a joint
collaborative programme of IMD with Indian Space Research
Organisation.
