Abstract :
Presents a new system to measure physical snowfall parameters using image processing techniques. It is possible to calculate the snowfall rate from the mass and volume of each snow particle. Using image data, it is also possible to calculate the radar reflectivity Z, assuming Rayleigh scattering and discrete data. The relationship between X-band wave attenuation, Z and snowfall rate was investigated and compared to the characteristics of snow particles. It was suggested that the power spectrum is related with the content of ice crystals
