Doppler Radar

Weather Radars are the basic and most important tool for a Meteorologist for Nowcasting and Forecasting of various severe weather events. We at SGS Weather are executing the network of 12 numbers S Band Metstar WSR-98D with Vaisala signal processor and IRIS application software in India. The WSR-98D combines state-of-the-art technologies with proven off-the-shelf components to create a system that is reliable and easy to operate. In addition to its very attractive up-front cost, WSR-98D is also extremely cost-efficient to maintain. S band radars operate on a wavelength of 8-15 cm and a frequency of 2-4 GHz. Because of the wavelength and frequency, S band radars are not easily attenuated. This makes them useful for near and far range weather observation. The size of the Antenna is 8.5 meters and it requires a large motor to power it.
