Z-R relation for snowfall using two small doppler radars and snow particle images

Snowfall data was simultaneously recorded by two small Doppler radars, two high sensitive snow gages and an image processing system with high accuracy at short time interval. The snowfall rate R was measured with two gauges and radar reflectivity factor Z was measured using small bistatic X-band radar and monostatic K-band radar. The images of falling snow particles were used to obtain size distribution. Since all the measurements were located in a small area, it can be said that the obtained data corresponds well to others, and it is possible to analyze Z-R relation in detail. The relationships between two radar reflectivity factors and snowfall rate were investigated and compared to the characteristics of snow particles.
