Fitted and corrected Chinese nighttime light dataset from 1992 to 2022

Through steps such as projection resampling, sensor saturation correction, intra-annual correction, and time series continuity correction, as well as the spatiotemporal consistency fusion of two generations of sensor data achieved through a univariate quadratic regression mathematical model, a long-time series nighttime light dataset spanning from 1992 to 2022 was constructed. The spatial resolution of this dataset is 1000m, and it is stored in the format of xxxx.tif, where "xxxx" represents the year, starting from 1992 and ending in 2022, covering a total of 31 years of data.
