Hi, I´m trying to do some temporal analysis using band 6 from landsat 5. I have two scenes: one from november 1989 and another from november 2005. Does anyone knows whether atmospheric corrections are sufficient enough to do such analysis? In my view, the biggest problem would be to quantify the temperature differences pixel-by-pixel, since the downwelling and upwelling radiant energy will be different, even if just a little bit, thus affecting my results. If so, what would be the best method? mono-window, split-view.... appreciate,
I'm working on a project right now and I want to make sure that I get the radiometric corrections perfect and I've heard that thermal bands are different from 1-4. I was told that you can't just use darkest object subtraction or a cos(t) model, but that you have to have a different approach altogether. I'm going to be using LandSat8's TIRS (bands 10,11) to try to discern an estimate of surface temperature. The image that I have is relatively free of cloud cover, but I want to make this image as clean as possible so as to not accidentally calculate the Top of Atmosphere temp. Any help would be awesome!
