No, the "8" value is both the RAW and BRIT (brightness) values. re: > because it is either 8 or 4 or 12 in all of the files. Given the very low value of the RAW/BRIT values, your images are in conditions of low light. I believe that a Google (tm) search using 'GOES 7 albedo' will show a number of useful studies of calculation of albedo for GOES-7.
