ABSTRACT
The IR limb emission of the lower stratosphere has been measured using a balloon-borne liquid nitrogencooled Michelson interferometer with liquid helium-cooled Si:Ga detectors. Portions of the thermal emission spectrum have been recorded between 650 and 2000 cm(-1) with an unapodized spectral resolution of 0.03 cm(-1). This is the highest spectral resolution limb emission thus far obtained. A preliminary description is given of these data along with a discussion of the significant features. Species identified to date include CO(2), O(3), CFCl(3), CF(2)Cl(2), H(2)O, CH(4), HNO(3), N(2)O, NO(2), and ClONO(2). A tentative identification is made for NO, representing the first direct spectroscopic detection of NO in emission.
ABSTRACT
The frequencies of CO(2) lines in the 3.77-4.26-microm region, which were obtained experimentally, have been compared with those listed on two tapes of the AFCRL Atmospheric Absorption Line Parameters Compilation. The experimental line frequencies were obtained in absorption using a high-resolution Michelson interferometer. Discrepancies between the present experimental values and the frequencies listed on the AFCRL tapes are tabulated. Consistency checks were also made by comparing calculated line frequencies with those on the tapes, and these findings are also reported.
