摘要
The effects of methane, ozone, water vapor and nitrous oxide on the retrieval of tropospheric CO profiles using correlatinn radiometer have been assessed. The scheme of the retrieval in the presence of solid clouds have been proposed. The effect of methane and nitrous oxide can be well accounted by their mean profile, and that of ozone can be represented by a typical middle latitude ozone profile, while for water vapor, less than 50% uncertainty is required. With the assumption of blackbody for cloud surface, the CO profile may be retrieved for low and middle solid clouds.However, the retrieval of CO profile will lose quality for high clouds.
