Description

These data consist of calibrated soil moisture sensor measurements recorded by manual sampling teams at the field sites of SMAPVEX16-Iowa during two intensive observation periods in June and August of 2016. The sites were located throughout an experiment domain of about 30 km by 40 km approximately 30 km north of Ames, Iowa.
