The values in parentheses represent the reduction rate of error between the data of this station and WHL data. Negative numbers indicate a decrease in prediction error, while positive numbers indicate an increase in prediction error. The calculation formula is: Reduction rate = ((other station data – WHL station data)/WHL station data) * 100%
