To date, RSE Kazhydromet receives radar data from 3 Doppler Meteorological radars (hereinafter referred to as Doppler radars) located in three regions of Kazakhstan, such as Taldykorgan, Torgai and Balkhash.
DMRL is a technical means operating on the basis of a magnetron in the frequency range of centimeter wavelengths, with the ability to operate in the dual polarization mode.
The principle of operation of all FMRLS is based on the use of reflection (radio echo) of electromagnetic waves by observation objects within a radius of up to 200 km. Such a phenomenon is called a radio echo, and in order to detect it, a directional and coordinated radio transmitter and a highly sensitive radio receiver must be present in the design of each FMRL.
The main output information of radar meteorological observations is information about the location, internal structure, meteorological characteristics (type of weather event, intensity and phase of precipitation, upper cloud limit, Doppler velocity) of cloud and precipitation fields, as well as observations of their movements and evolution, with the possibility of ultra-short-term (up to 1-3 hours) weather forecasting.
Today, meteorological radar networks have been established in all developed countries: in the United States, the NEXRAD or Nexrad (Next-Generation Radar) network is a network of 159 high—resolution S-band Doppler weather radars operated by the National Weather Service (NWS), the agency of the National Oceanic and Atmospheric Administration (NOAA), in Europe as part of The OPERA international project brings together about 180 radars from various manufacturers operating under different observation programs. More than 100 workstations of the MARS meteorological automated radar network have been installed in the meteorological divisions of the Russian Federation's Roshydromet.
