Aerosol optical depth

one of the important parameters to describe the property of aerosol

is widely used in the region of Radiative Transfer and Atmospheric Correction; but at the same time

Meteorological Range but not Aerosol Optical Depth is used as an input parameter for the famous Radiative Transfer program: MODTRAN. It is reasonable to get the relative between Aerosol Optical Depth and Meteorological Range for the convenient using of all kinds of aerosol data. Though there are many expressions to describe the relative between them

the analysis in this paper shows that their relative change with the season change of aerosol profiles. An empirical expression was given here based on the simulation using MODTRAN4

and the coefficient of formula is different with the seasonal change of aerosol profiles. If this difference is ignored

the error of aerosol optical depth error may reach the level of 0.029 when the same meteorological range is transformed.
