High-Resolution Soil Moisture Product for India, 1981-2024

This dataset provides daily root-zone soil moisture (RZSM) estimates over India at 0.05° (~5 km) spatial resolution for the period 1981–2024. The data were generated using a machine learning approach that combines outputs from the calibrated H08 land surface model with SMAP satellite observations. A grid-wise Random Forest model was trained using data from 2016–2024, with input features including H08-simulated soil moisture, evapotranspiration, precipitation, and temperature. The resulting dataset offers high-resolution, long-term soil moisture estimates tailored for hydrological and agricultural studies across India.
