Figure 7 presents the comparisons between ground observations and three
downscaled results for each year. The CDFs of SSM measured by in-situ
and downscaled results derived from three different algorithms are
displayed in Figure 8. The performance shown by the four statistical
metrics appears inconsistent from year to year when comparing the
results of SVRK and SVRB methods. The SVRK results are frequently better
than the SVRB’s during the five-year period. In general, the SVATARK
model produces the two highest statistical metrics (i.e., R andSLOP ) and the two lowest statistical metrics (i.e., RMSEand MAE ), followed the SVRK and SVRB models. The CDF comparison
indicates that the downscaled results of SVATARK models show minimum
deviations from the CDF calculated from the ground observations.
