Modeling soil moisture from rainfall: An evaluation of the diagnostic soil moisture equation

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The diagnostic soil moisture equation (DSME), which estimates soil moisture from antecedent precipitation, can be used to gap‐fill and extend existing in situ records. We train and evaluate the DSME at 157 Soil Climate Analysis Network and 113 US Climate Reference Network (USCRN) stations across the contiguous United States.

Comprehensive Analysis of CYGNSS GNSS-R Data for Enhanced Soil Moisture Retrieval

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Soil moisture, an essential climate variable, is traditionally retrieved on large scales using passive or active microwave sensors, with temporal resolution of 2–3 days and no less than 6 days, respectively.

NIR-Red Spectra-Based Disaggregation of SMAP Soil Moisture to 250 m Resolution Based on SMAPEx-4/5 in Southeastern Australia

Remote Sensing, 2017
To meet the demand of regional hydrological and agricultural applications, a new method named near infrared-red (NIR-red) spectra-based disaggregation (NRSD) was proposed to perform a disaggregation of Soil Moisture Active Passive (SMAP) products from 36
