Abstract:
Ground (soil) temperature data recorded by temperature data recorders buried in 1 cm and 10 cm depths of the ground surface at mid range of Yukidori Zawa during the JARE-51 and 53 (2010-2012) was summarized in a table. Almost 2-year data of the ground temperature at two discrete depths were compiled in a text file from each recorder at 1-hr interval. Using the present data with air temperature and solar radiation data from neighborhood automatic weather station reported previously, timing and period of soil thawing were graphically shown.
