AbstractThis dataset consists of 9855 records of measurement data of heat balance/water balance observation, taken in 2025, at the Heat and Water Balance Measurement field in Tsukuba city, Japan. The parameter is as follows; wind direction, wind speed, momentum flux, sensible heatflux, shortwave radiation, downward longwave radiation, net radiation, soil heat flux, air temperature, soil temperature, dew point temperature, ground water level, pan evaporation, precipitation, relative humidity, air pressure and sunshine duration. The observation started on August 1st, 1981 and has been ongoing for more than 45 years.
