Soil Moisture Data
Soil moisture is an essential component of the Earth system and plays an important role in the exchange of water, energy and biogeochemical fluxes between the atmosphere and the land surface. Temporally and spatially continuous soil moisture datasets are commonly explored through hydrological and land surface models.
Beyond in situ measurements and model simulations, remote sensing provides another path to estimating soil moisture, which can provide independent reference data for validating model simulations, while avoiding the spatial coverage limitations of ground-based measurements. Optical, thermal infrared, and microwave remote sensing observations have all been used to retrieve soil moisture.
