Daily Root Zone Soil Moisture and Meteorological Dataset for Time Series Prediction (2020–2025)

This index reflects the relative degree of soil moisture saturation in the root zone rather than absolute volumetric water content (m³/m³). The soil moisture data correspond to the same geographic coordinates as the meteorological station (latitude −7.0398, longitude 113.914). All variables were aligned on a daily temporal scale.

Special codes for missing or unavailable values (e.g., −999) were identified and handled during preprocessing. Zero rainfall or zero sunshine duration represent valid observations rather than missing data. The dataset is structured for supervised learning, where meteorological variables serve as input features and the GWETROOT soil wetness index serves as the prediction target.

The dataset is suitable for time series forecasting, environmental modeling, irrigation recommendation systems, and agricultural decision support applications.
