Re: why Aerosol Optical Thickness of MOD04_l2 range that i read from file is -10 to 2 and

I've never heard of that program or toolbox, and I don't even understand what the "problem" is. Some code gives you numbers in the range of [-10 to 2] instead of [0 to 10] like you expect? Well what can we do to help you other than suggest your code is wrong or you're inputting the wrong input parameters? Why don't you debug your code with the built-in debugging tools???
