Description GSM3 (Global Soil Moisture from a Multitask Model, v1.0) is a daily, 9 km global soil moisture dataset spanning 2015–2020. It was generated using a multitask deep learning model that simultaneously learns from multiple soil moisture networks worldwide, enabling robust generalization across diverse climatic and land cover conditions. The dataset and methodology are described in detail in the companion paper below.
