Short summary

A big challenge for accurate cloud detection is the inhomogeneous brightness distribution of sky background, which mainly caused by the difference in atmospheric scattering angles. In this manuscript, we report a new RGB channel operation aiming to remove this inhomogeneous sky background in the total sky images, and then a cloud detection algorithm based on this new channel is proposed which combined the merits of the threshold and differencing methods.
