摘要：
The high radiation intensity and weak self-absorption effect of the O2（a1∆g）airglow in the 1. 27 μm band make it an ideal target source for retrieval of the atmospheric temperature in the near-space. Based on the theory of O2 airglow spectral and the "onion-peeling" algorithm，the near-infrared limb-viewing data of the SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY（SCIAMACHY）were successfully used to retrieve the atmospheric temperature profiles in the range of 50-100 km. Comparison with SABER，ACE-FTS and LIDAR observations shows that the temperature measurement error is better than ±10 K in the tangential altitude of 55-85 km. However，in the space region below 55 km and above 85 km，the temperature retrieval results show significant bias due to the influences of self-absorption effects，atmospheric scattering，and spectral contamination from OH airglow. © 2024 Chinese Optical Society.
