Hello, I am using MODIS level 1b and trying to extract the brightenss temperature for bands 31,32 to calculate SST. The ENVI gives me values of the emissive band 31 about 10000 when i don't use auto-correct MODIS(which make use of gain and offset) and about 9 when i use it! Is it normal?? I don't think that these values are radiances. I am confused. Any help would be appreciable! Thanks in advance
