    33This page contains some basic processing instructions for atmospherically correcting ARSF data using ATCOR. Note try and do everything in the correct order - if you do later parts of the process first it sometimes resets them when you do the earlier ones (depending on exactly which ones). This is a basic guide only, you may well be able to get better/more accurate results using more advanced bits of ATCOR.

     5'''Caution:''' ATCOR changes the output from radiance to reflectance. So where level 1 files (and therefore level 3 files that were not corrected using ATCOR) are in units of uW/cm2/sr/nm * 1000, level 2 files (and therefore level 3 files that have been corrected using ATCOR) are in units of percent radiance * 100. Note the scaling factors can be changed by the user.
