Satellite Soil Moisture Data
Microwave satellites measure near-surface soil moisture at continental scale, filling a gap that ground networks never covered well: SMAP, ESA CCI Soil Moisture and ASCAT are the standard products, used for drought monitoring, model calibration and antecedent-moisture inputs to rainfall-runoff models.
The longest satellite soil moisture record available — merged active+passive retrievals back to 1978, free, no login.
