Abstract  

A new kind of tropospheric aerosol extinction coefficient profile retrieval method with hyper-spectral (0.05 nm) reflected information in oxygen A band is presented.The advantage of this novel method is the Aerosol Optical Depth (AOD) restriction is considered.As two correction factor M and D are introduced,Lagrange multiplier could be chosen automatically and the precision of retrieval increased.To test this method,we do the simulation retrieval with the help of CALIPSO Level 2 aerosol products and new hyper-spectral resolution RT model.Two types of aerosol scene are selected:dust event and clean condition.For dust event,the relative retrieval error is 51%,while in clean condition,the error could be controlled under 20%.If revise profile is added,the retrieval precision will be much better.

Key words:  Oxygen A-band      Aerosol extinction coefficient profile      Aerosol optical depth restriction      Hyper-Spectral resolution      Retrieval
