The adjusted urbanization bias monthly temperature dataset was developed based on the records from 763 national meteorological stations of China (1961-2015). To adjust the data from a target station, the reference stations were used within 300 km around the target station. Among the reference stations, four were chosen where correlation coefficient between trends removed annual average temperature series of the reference stations and the target stations were the largest and passed the significance test of significance level at 0.005. Then, the square of the correlation coefficient of the annual average temperature series of each reference station and its target station was used as the weight, and the weighted average of the monthly average temperature of the reference stations was calculated as the reference sequence. And following, the difference of the trends between the city station sequence and the reference sequence was used to adjust the data at target station linearly. Finally, the inverse distance weighted interpolation method was used to interpolate the temperature data of 763 stations nationwide into grid data of 2 ° x 2 °. To test the accuracy of the dataset, Beijing, Wuhan, Yinchuan and Shenzhen were selected as the representative stations of large cities in North, Central, Northwest and South China. Their relative urbanization biases were 67.0%, 75.4%, 32.7% and 50.3% in the past 55 years, respectively. The dataset was archived in .txt data format, and each file was named according to the year and month. In each file, it is composed of a header file and 18 rows and 32 columns of average temperature (℃) data. The first 6 rows are header file, which are the number of columns, the number of rows, the longitude in the lower left corner, and the latitude in the lower left corner, missing value. The dataset consist of 660 data files with data size of 2.75 MB (Compressed to one single file with data size of 895 KB). The analysis paper based on this dataset was published at Progress in Geography, Vol.38, No.4, 2019.Browse
