Abstract: A Fourier phase difference technique for cloud motion estimation from pairs of pictures is described. This technique makes use of the phase of the cross-spectral density; it allows motion estimates to be made for individual ...

Abstract: A physical-statistical model using Nimbus II MRIR (medium resolution infrared) radiometer channel 2 (10?11 µm) data is formed to estimate cloud cover. In the model, cloud cover is estimated from the probability density ...
