NPP-VIIRS interannual night time light remote sensing dataset for the Sahel-Sudano-Guinean region of Africa (2013-2020)

NPP-VIIRS interannual night time light remote sensing dataset for the Sahel-Sudano-Guinean region of Africa (2013-2020)


The data set contains annual NPP-VIIRS night time light data images of equatorial northern Africa and the Sahel region from 2013 to 2020. Based on the monthly average night time light image data of visible infrared imaging radiometer Suite (VIIRS) of national polar orbiting partnership (NPP) satellite, this dataset is generated by separating the unstable night light caused by biomass combustion from the stable night light information caused by human activities. The spatial resolution of the data is 500 m, and the grid data type is GeoTIFF. The grid pixel value is radiance, and the unit is 10 − 9 w ∙ cm − 2 ∙ SR − 1. The data set improves the ability of noctilucent images to identify small-scale, scattered and unstable urban information in northern equatorial Africa and Sahel to a certain extent, and can be further applied to the research on human activities in northern equatorial Africa and Sahel.


File naming and required software

File name: the data is stored in GeoTIFF format. The file name is "viirs_annual_yyyy. TIF", where yyyy represents the year.
Data reading method: software or computer language that can read GeoTIFF can read the data, such as ArcGIS, envi, IDL, python, MATLAB, etc.
