A Modified Spatiotemporal Mixed-Effects Model for Interpolating Missing Values in Spatiotemporal Observation Data Series

Table 6

The RMS values of residuals of the interpolated results for the artificial gaps of 100 days with 209 stations (unit: mm).

Site	MSTME	KKF	STME	Improvement 1 (%)	Improvement 2 (%)
7ODM-U	8.3	10.4	9.1	20.2	8.8
BKMS-U	2.1	2.5	2.9	16.0	27.6
BSRY-U	2.3	2.9	3.8	20.7	39.5
HOGS-U	2.0	2.6	2.7	23.1	25.9
Average	3.7	4.6	4.6	19.6	19.6

The “Improvement 1” is the improvement rate of the MSTME model over KKF model, and the “Improvement 2” is the improvement rate of the MSTME model over STME model.
