Abstract

Atmospheric emission measurements with the cryogenic airborne Michelson Interferometer for Passive Atmospheric Sounding revealed strongly disturbed phase and magnitude spectra. They were corrected with the double-differencing method: The phase information implied in the line structure of atmospheric spectra is used to specify a phase shift with respect to an instrumental phase spectrum, which was determined once from calibration measurements with the differencing method of Revercomb et al. [Appl. Opt. 27, 3210 (1988)].

摘要

利用用于被动大气探测的低温机载迈克尔逊干涉仪进行的大气发射测量揭示了相位和幅度谱受到强烈干扰。采用双差分法对其进行校正：大气光谱线结构中隐含的相位信息用于确定相对于仪器相位谱的相移，该仪器相位谱曾通过Revercomb等人的差分法[《应用光学》27, 3210 (1988)]从校准测量中确定。
