DMRL-C
DMRL-C (Cyrillic: Доплеровский Метеорологический РадиоЛокатор, ДМРЛ, Engl.: Doppler-Weather Radar) is operating in C-Band polarimetric weather radar. The transmitter's power stage is fitted with a klystron. The symmetric parabolic reflector has a diameter of 4.3 m. Its weight is 244 kg. This type of radar was developed between 2008 and 2012. The inspiration for some technical solutions was the polarimetric weather radar Meteor 635-C of the company Gematronic GmbH (Neuss, Germany).
DMRL-C is designed for:
- displaying the distribution of various meteorological data (reflectivity, speed, spectrum width, as well as in the double polarization mode: differential reflectivity, phase, cross-correlation coefficient and linear depolarization ratio) at different altitude levels on the type of pseudo-CAPPI;
- calculation and display of the vertical velocity profile, wind direction up to the height of the upper limit of detection of meteorological objects, maps of vertical and horizontal shift of wind and turbulence;
- calculation and display of precipitation intensity for any time interval;
- Determination of dangerous weather phenomena (hail, thunderstorm, storm surge, heavy rain and snow, heavy turbulence);
- displaying the speed and direction of movement of cloud systems;
- Issuance of radar information in the required coding diagrams
Note: The origin of the letter “C” in the original Russian designator is not the Cyrillic «С» (spoken as [ʔɛs]) but the Latin letter “C” (spoken as [t͡seː]) for the used frequency band! However, this letter is often read as “S” in Russian context.
