Accurate temperature measurements are fundamental to studies of the Earth's atmosphere. Temperature profiles are essential for interpreting atmospheric remote sensing data since temperature uncertainties usually lead to large uncertainties in other parameters such as gas concentrations. Solar occultation measurements of limb path transmittance from the HALogen Occultation Experiment (HALOE) on UARS and the Solar Occultation for Ice Experiment (SOFIE) aboard AIM have been used successfully to derive temperature vs. pressure (T(P)) profiles. Refraction measurements from GPS satellites have also been used to derive T(P). (Ware, et al., 1996). Ward and Herman (1998) demonstrated that passive refraction measurements could be used to derive T(P) profiles, but the precision required for accurate stratospheric temperatures appeared impractical. In a new approach described here, we use solar extent data from SOFIE to precisely calculate the refraction profile, and derive T(P) profiles from the troposphere to the mesosphere. Additionally, SOFIE measures carbon dioxide transmittance profiles with exceptionally high precision, providing an independent T(P) retrieval that extends up to the lower thermosphere. The refraction angle and transmittance profiles are registered in altitude to very high accuracy. Here we present an overview of both methods, including features and limitations of each. We compare and discuss results obtained from applying each method to the SOFIE measurements. We further discuss the benefit of using a combined iterative approach, and present preliminary results from this. Finally, we offer conclusions and suggestions for future missions. Ward, D., and B.
