The data set mainly covers long time sequence night light information in mainland China. The data storage format is GeoTIFF, and the spatial resolution is 1-km. The processing method is to simulate the relationship between NPP-VIIRS data and DMSP-OLS data. NPP-VIIRS data from 2013 to 2020 is used to simulate DMSP-OLS data from 2013 to 2020, so as to obtain a similar DMSP-OLS dataset from 1992 to 2020. Firstly, the nuclear density method is used to resample the spatial fraction of NPP-VIIRS data to 1-km. Based on the "S" curve relationship between the resampled NPP-VIIRS data and DMSP-OLS data after logarithmic conversion, the sigmoid function is used to convert the logarithmic NPP-VIIRS data into analog DMSP-OLS data. The DMSP-OLS data calibrated from 1992 to 2013 and analog DMSP-OLS data from 2013 to 2020 are spliced into similar DMSP-OLS data from 1992 to 2020
The data naming method from 1992 to 2013 is DMSPyyyy.tif
Data naming method from 2013 to 2021: DMSP-likeyyyy.tif
