Intercalibration Between Night-Time DMSP/OLS Radiance Calibrated Images and NPP/VIIRS Images Using Stable Pixels

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In this study, we proposed a method for intercalibration between DMSP/OLS radiance calibrated images and NPP/VIIRS images based on stable pixels, while the challenge is that these two datasets do not have overlapped periods which makes it ...
