IMD operates a network of hundreds of surface and glacial observatories, Upper Air (high altitude) stations, ozone and radiation observatories and meteorological radar stations. Additional data is received from India's constellation of satellites, such as Kalpana-1 , Megha-Tropiques and instruments on board the IRS series and the INSAT series ...
The CP2 Research radar was a 1970's era radar, which the BoM received as a gift from the NCAR in the United States. The BoM retrofitted it with modern parts which gave it the unique ability to collect data at two frequencies, S and X band. The upgrades also provided state of the art dual polarisation and doppler technologies.
A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
The Precipitation Radar (PR) was the first space-borne instrument designed to provide three-dimensional maps of storm structure. The measurements yielded information on the intensity and distribution of the rain, on the rain type, on the storm depth and on the height at which the snow melts into rain. The estimates of the heat released into the ...
English: Height of a radar beam above Earth (AGL). Calculation of the height of radar echoes in the operating principles. Assuming the Earth is round, the radar beam in vacuum would raise according to the reverse curvature of the Earth. However, the atmosphere as an refractive index that diminish with height, due to the variation of its density.

The main instrument in this research was an S-band circularly polarized weather radar located at the Red Deer Industrial Airport in central Alberta, Canada. A vast amount of data was collected from several other platforms to conduct research into precipitation mechanisms, severe storm development, hail suppression, hydrology and microwave ...
