Meteorological and snow profile observation data at Tohkamachi Experimental Station, Forestry and Forest Products Research Institute, Japan (X) (2019-20 to 2023-24, five winter periods)

Abstract

The Tohkamachi Experimental Station of the Forestry and Forest Products Research Institute has been conducting meteorological observations since 1918 and snow profile observations since the winter of 1939–40. This report aims to provide fundamental data on snow phenomena observed at the Tohkamachi Experimental Station. The report summarizes the results of meteorological and snow profile observations during five winter periods from 2019–20 to 2023–24. The meteorological observations include weather, air temperature, daily precipitation, snow depth, daily snowfall depth, and snow water equivalent, measured daily at 09:00. Snow profile observations were conducted approximately every ten days to measure the snow layer structure and the vertical distribution of physical characteristics such as grain shape, grain size, snow temperature, snow density, snow hardness, and water content.
