Datasets description

  This dataset is based on daily temperature/ground temperature data from 66 meteorological stations on the Qinghai Tibet Plateau from 1980 to 2020. The atmospheric freezing index/ground freezing index from 1980 to 2020 is calculated, and the average freezing N coefficient and its slope for each meteorological station from 1980 to 2020 are obtained; Calculate the atmospheric melting index/ground melting index from 1980 to 2020, and obtain the average melting N coefficient and its slope for each meteorological station from 1980 to 2020.

  The content of the N coefficient table for meteorological stations on the Qinghai Tibet Plateau from 1980 to 2020 is as follows:

   Nf: Annual average ± standard deviation of frozen N coefficient from 1980 to 2020

   Nt: Annual average ± standard deviation of melting N coefficient from 1980 to 2020

  Slope_Nf: Slope of frozen N coefficient from 1980 to 2020

   Slope_Nt: Slope of the variation of melting N coefficient from 1980 to 2020

Data source description

  The temperature/ground temperature data from meteorological stations is sourced from the China Meteorological Data Network（ http://data.cma.cn/ )

Data processing method

  If the data is missing for one day, replace it with the average temperature of the adjacent day; For two consecutive days of missed measurement, the first day of missed measurement shall be filled with the average value of the data of the previous two days, and the second day of missed measurement shall be filled with the average value of the data of the following two days. If the test is missing for two days or more, the data of the same period of the previous year shall be used to supplement

Data quality description

  The daily average ground temperature data of 11 meteorological stations are greater than zero, and the freezing N coefficient is zero; P value of change slope of freezing N coefficient and melting N coefficient is less than 0.05
