Hi Seyed,

The AODs at different wavelengths are mutually connected by the following equation:

AOD(wl_2)/AOD(wl_1) = (wl_1/wl_2)^A

where wl_x denotes the wavelength. A denotes the Ångström exponent. More details could be found in Marseille et al.(2011), The definition of an atmospheric database for Aeolus

Hope it helps.

Sincerely yours,

Yongbo

Dear Yongbo ,

Thanks for your reply. This works for the determination of normal AOD at given wavelength with respect to known normal AOD at the other wavelength using the Ångström exponent . But, I meant the conversion of normal AOD to deep blue AOD.

Best,
