SMAP-HydroBlocks: Hyper-resolution satellite-based soil moisture over the continental United States

SMAP-HydroBlocks (SMAP-HB) is a hyper-resolution satellite-based surface soil moisture product that combines NASA's Soil Moisture Active-Passive (SMAP) L3 Enhance product, hyper-resolution land surface modeling, radiative transfer modeling, machine learning, and in-situ observations. The original dataset was developed over the continental United States at 30-m 3-hourly resolution (2015–2019). This dataset is an aggregated product and is available for download at a 1-km 6-hr resolution. Visualization is available at https://waterai.earth/smaphb/, and subsets of the original dataset are available on request from Noemi Vergopolan ([e-mail]). The SMAP-HB dataset reports the top 5-cm surface soil moisture in volumetric units (m3/m3). The files have a Plate Carrée projection and are stored in netCDF4 format.
