Map of the study area: provincial administration regions of Mainland China and the geographical locations of all 839 meteorological observation sites (brown dots) within it. These sites provide T_a observations called hard data. The study area was divided into two parts: the west part and the east part with a dividing line (called Hu Huanyong line in the name of Chinese scholar Hu Huanyong). According to the elevation, three terrain ranges are demarcated (brown lines). The pink dots are supplemented locations to calculate soft data (totally 334 locations).
