  1. 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,
  2. Would anybode know whether the radiometric properties such as Solar Spectral Irradiance are the same for QUICKBIRD 01 and 02?
