| Outline of Final Research Achievements |
We developed the new snowfall phenomenon measuring system in the lowest atmospheric layer. The radar reflectivity factor and spectrum were measured using three small K-band Doppler radars and lidar. The image of falling snow particles were simultaneously captured to measure size and falling velocity. Furthermore, the rainfall particle information with the weather sensor was analyzed. The precipitation intensities of rainfall and snowfall were calculated. The radar reflectivity factors of radar and lidar were compared with these intensities.
