Doppler radar reflectivity

WebJun 25, 2024 · Measures radar reflectivity, Doppler velocity, linear depolarization ratio, and differential reflectivity. The Doppler velocity values are corrected for the motion and orientation of the aircraft. CRS has two operation modes. When CRS operates in ER-2 mode, it can measure reflectivity, Doppler velocity, and linear depolarization ratio. WebReflectivity, , is the zeroth moment of the Doppler spectrum and is related to liquid water content or precipitation rate in the resolution volume. Because values of that are commonly encountered in weather observations span many orders of magnitude, radar meteorologists use a logarithmic scale given by as dBZ, where is in units of mm^6/m^3.
