And attached is figure output of the 6 aerosols total AOD by using sum function in GrADS software.

But the values are between 0.-0.1 which are much less than normal AOD values(0.-1.0, seen as attached MODIS observation output)

Are the simulated values right?

I can't find out which step I was wrong.

Has anyone done similar experiments?

Please give me some advices about this.

Thank you very much in advance.
