| Research Abstract |
This research considered the observation technique of snow coverage using the portable type microwave radiometer. This method is effective as a wide range and safe snow coverage survaey at the time of heavy snow disaster. From the observation experiment in the cold laboratory and winter snow field, snow coverage and freezing/dissolution parameter which influences microwave radiation was measured.
On the other hand, numerical simulation of the snow coverage layer was also performed. Verification of the model was performed using data from Kitami, and, as a result of snow change was comparatively good.
Comparing with cross-sectional observation of snow at Kitami, the snow density and snow temperature in the cold regime were well in agreement. Simulation of snow type showed development of granular snow as depth hoar. This research used the snow coverage change simulations which are a microwave radiation meter which is the newest measuring instrument, and the newest technology. The view of the new observation method was attempted in this project.
