%X This data set is based on the daily temperature/ground temperature data of 66 meteorological stations on the Qinghai Tibet Plateau from 1980 to 2020. The atmospheric freezing index/ground freezing index from 1980 to 2020 are calculated, and then the multi-year average freezing N coefficient and its change slope of each meteorological station from 1980 to 2020 are obtained; Calculate the atmospheric melting index/ground melting index from 1980 to 2020, and obtain the multi-year average melting N coefficient and its change slope for each meteorological station from 1980 to 2020. The N coefficient table of Qinghai Tibet Plateau meteorological stations from 1980 to 2020 is as follows: Nf: multi-year mean value ± standard deviation of frozen N coefficient from 1980 to 2020 Nt: multi-year average value ± standard deviation of melting N coefficient from 1980 to 2020 Slope_ Nf: change slope of frozen N coefficient from 1980 to 2020 Slope_ Nt: change slope of melting N coefficient from 1980 to 2020
