Luojia nighttime light data with a 130m spatial resolution providing a better measurement of gridded anthropogenic heat flux than VIIRS

Downscaling satellite night-time light imagery while addressing the blooming effect

“…The Luojia1-01 imagery was, first, georeferenced using 30 carefully selected control points throughout each study region. The images were then re-projected to one of the projection systems, contingent upon the study region, and resampled using the spatial average to 130 m [38]. The following equation was then used to convert the image DN to radiance values, based on laboratory calibration data from the satellite data website:…”
