Atmospheric Temperature Profiles from Earth Limb Infrared Measurements

摘要

This report describes the work accomplished on the retrieval of stratospheric temperature and density profiles from remote earth limb-view infrared radiation measurements. Temperature or density can be retrieved in a routine manner. A model based on two rotational lines of C02 was developed to retrieve simultaneously both temperature and density. This model is running on a CRAY-1 Computer but needs additional verification. An investigation of alternative methods to calculate infrared transmittance has showed that an interpolation scheme does not work for limb-view geometrics with a subsequent potential savings in computer time of one thousand or better. Though the concept has been proved, the ultimate accuracy of this method has still to be evaluated.
