Illinois Soil Moisture Data https://data.eol.ucar.edu/dataset/21.079 Summary This data set consists of total soil moisture measured at 19 stations in the state of Illinois, USA, from 1981 to November 2001, measured with the neutron probe technique, calibrated with gravimetric observations. The data are measured for the top 10 cm of soil, and then for 20 cm layers (e.g., 10-30 cm, 30-50 cm, ...) down to a depth of 2 m. The vegetation at all stations is grass, except for one station with bare soil measurements, at the same location as a grass-covered station. The measurements are at approximately monthly intervals.
