This dataset provides calculation samples and program code for the water temperature simulation model proposed in the paper. Program code is available in both VBA and Python versions. The VBA version includes calculation samples with input values and is compiled into an Excel file (XLSM). For the Python version of the program, sample input values (CSV) are provided separately for testing the calculation. Output values (CSV) are also provided for checking the calculation results.

These input values are based on observations at the experimental site in Saito, Japan (the location is shown in Fig. 3 of the paper). Observation was conducted from transplanting to harvest of rice in 2002. Additionally, for Python program code, a Japanese-annotated version is available that includes a function utilizing Agro-Meteorological Grid Square Data (AMGSD) as meteorological input values.

In the program code, the leaf area index (LAI) and canopy height (h) of rice are calculated from developmental stage (DVS: denoted as phenological stage Ps in the paper) using a crop growth model. Time step for the crop growth model is 1 day. On the other hand, time step for the energy balance model is 1 hour. The calculation includes a 10-day spin-up period to obtain water temperatures after eliminating the influence of initial values. Using the energy balance model, Canopy temperature and energy balance components including latent heat flux (evapotranspiration) are also calculated simultaneously with water temperature.
