Ation procedures. The values of 4 error indicators are distinguished in color degree–light blue indicates a larger value, dark blue indicates a smaller sized value. The smaller sized the error indicator, the greater the Pyrroloquinoline quinone Cancer interpolation technique plus the higher the accuracy in estimating the spatial patterns of precipitation. General, interpolation models estimate the spatial patterns of precipitation to a affordable degree; however, outliers appear at some stations. As an example, meteorological station 15 has the biggest estimation error, Pretilachlor supplier followed by meteorological station 18. The estimation anomaly for a specific spatial place may be attributed towards the complicated weather variability [38] triggered by the large elevation variations [45] in Chongqing, which could influence the overall performance of interpolation process [33]. 4.4. Complete Ranking by Entropy-Weighted TOPSIS To figure out the optimal system for estimating spatial precipitation patterns in Chongqing, Entropy-Weighted TOPSIS was adopted to quantize and rank the performance of six interpolation approaches. According to the overall performance evaluation indices (MSE, MAE, MAPE, SMAPE, NSE), the six interpolation approaches are ranked with regards to their efficiency in estimating spatial patterns under unique rainfall magnitudes and integrated several rainfall magnitudes. 1st, the indicators are standardized, where MSE, MAE, MAPE, SMAPE are adverse indices and NSE can be a optimistic indicator. Based on weighting final results of entropy system, the distance involving optimistic and negative perfect solutions of every approach is calculated to identify the comparatively proximity (C-value) to the ideal resolution, and finally the C-value is ranked to qualitatively evaluate the performance of six strategies in estimating the spatial pattern of precipitation in Chongqing below distinct climatic conditions. The calculation benefits of TOPSIS evaluation are shown in Table 2. As outlined by TOPSIS evaluation, KIB would be the optimum interpolation technique under the imply annual precipitation pattern, using the comparative proximity (C-value) the highest at 0.964, followed by EBK. RBF may be the optimal strategy within the rainy-season precipitation pattern, with the C-value the highest at 0.978, followed by KIB. KIB was the optimal approach inside the dry-season precipitation pattern, together with the C-value the highest at 1, followed by OK. IDW was the worst strategy within the all precipitation patterns, together with the C-value was the lowest to 0 without having exception.Table two.
