A method research on atmosphere molecule extinction optical depth

To achieve the accurate atmosphere aerosol extinction optical depth in area of climate and image inversion, the calculation of atmosphere molecule extinction optical depth was researched. A solving model for atmosphere molecule extinction optical depth was established, and every sub-model was simulated. Compared the results calculated by the model and the results calculated by PcModWin, relative error is within 5%. That provides the model for atmosphere molecule extinction optical depth is feasible and the model will be a foundation for engineering.
