Scientific data of monthly light pollution index for rivers of China

Firstly, the river sections in China are extracted from HydroSHEDS, , and the unreasonable river sections are corrected according to the authoritative river data; Secondly, the river sections layer and NPP-VIIRS grid are overlyed to identify the pixels flowing through the water system, and the value of each pixel is extracted from the NPP-VIIRS grid; Then, take 10 × 10km grid as the unit, comprehensively considering the flow, brightness and river length of each unit, the river light pollution index is designed, and the monthly river light pollution index of each unit is calculated; Finally, a dataset of monthly light pollution index of rivers with the resolution of 10 × 10km is generated.

As the first dataset of river light pollution, this dataset reflects the temporal and spatial distribution and evolution pattern of river light pollution in China, and can provide reference for river development degree and interference degree evaluation, light pollution analysis and other research.
