I wanted to let you know that I have enjoyed reading your blog. Your comment about avoiding "clouds blocking your pretty view" in your satellite images made me laugh. They're not so pretty when they are covering up your study area! Interference from the atmosphere has always been one of the biggest problems in remote sensing, and a large obstacle to radiometric accuracy. You could easily devote a whole blog post to Atmospheric Corrections that might be needed for an image even if you don't actually see puffy white clouds, since distortion from the atmosphere can make pixels in your image brighter than they would have been otherwise.
Anyway, I will continue to read and enjoy.
