Description :
The AA. investigate changes in the underlying surface of 756 meteorological stations across China from 1970 to 2007. They improved the accuracy in distinguishing stations using remote sensing images combined with practical investigations. The mean urban heat island effect intensity since 1970 was estimated by comparing the original observational records from urban stations with the background air temperature interpolated. The result shows that urban heat island effect does occur due to urban expansion, with a higher intensity in winter than in other seasons. Then the overestimation of regional air temperature is evaluated by comparing the 2 kinds of grid datasets of air temperature which are respectively interpolated by all stations’ and rural stations’ observational data.
