A gridded dataset of Extreme low temperature events over China-Pakistan Economic Corridor during 1961-2015

This paper is based on 0.25 ° in China Pakistan Economic Corridor × 0.25 ° resolution daily minimum temperature grid data. Firstly, input the daily minimum temperature grid data of China Pakistan Economic Corridor from 1961 to 2015. Then, check the data and eliminate the high-temperature area (the average annual daily minimum temperature of the grid point > the average daily minimum temperature of the study area). If there is no high-temperature area in the study area, the extreme low temperature threshold can be calculated directly without eliminating the high-temperature area. Then, the extreme low temperature threshold is calculated. From the grid data of daily minimum temperature in China Pakistan Economic Corridor from 1961 to 2015, the multi-year average value of the 5th percentile of the daily minimum temperature in winter (December to February) is selected as the threshold of extreme low temperature. After the extreme low temperature threshold is determined, the extreme low temperature events with different durations are identified. Next, the minimum impact area threshold of extreme low temperature events is set and then eliminated. Finally, the extreme low temperature events with different durations are identified. The comparison with historical extreme low temperature events shows that this data set has high accuracy and reliability. This data set is in *. Mat file format. After decompression, you can use MATLAB software to open, display, view, statistical analysis, etc. Because of the problem of data format, it is recommended to use MATLAB software for batch processing. Users can selectively download data according to the actual research situation.
