Determination of the melting layer from meteorological radar data

The bright band is the enhanced radar echo (reflectivity) associated with the melting of hydrometeors in stratiform rain. However, incorrect determination of the bright-band may lead to significant overestimation of precipitation such as rainfall rate reaching the ground, sometimes by as much as a f...
