Fig. 3. Simulated effect of the correction for temporal persistence on the relationship between actual and estimated layer-average water contents at the 15-cm depth. Number of probes removed: (a, b) from one to eight; (c, d) from one to four; (e, f) from one to two. Average water content over remaining probes before (a, c, e) and after (b, d, f) the correction application. Values of R2 are the determination coefficients and RSMD is the root-mean square differences of the linear regression actual vs. estimated average water contents.
