在1991年4月28日至5月6日的航天运输系统39（STS 39）飞行期间，航天飞机低温红外辐射仪器（CIRRIS 1A）使用迈克尔逊干涉仪测量了大气红外辐射的光谱和空间（“地球边缘扫描”）分布。在航天飞机飞行高度260 km处，利用9-13 μm大气红外窗口，采集了温室气体的红外光谱辐射。在飞行之前和之后，CIRRIS 1A对红外光谱发射源的响应使用绝对和光谱源类型进行校准。快速大气特征码3使用HITRAN 92数据库和国家气象中心预先确定的温度-压力剖面，用于洋葱去皮程序，从绝对校准的光谱数据（中等分辨率为1.0 cm−1）中检索气体浓度。O3、HNO 3、CFC-12和CFC-11的垂直分布图。误差分析表明，测量的光谱数据的质量和这些反演结果的准确性。对流层顶区域CFC-11（3.0×10−4 ppmv）和CFC-12（4.9×10−4 ppmv）的浓度与全球通量增加率约为5% yr−1相一致。观测到的HNO 3浓度与以前报告的相对干净的平流层一致。
During the Space Transportation System 39 (STS 39) flight of April 28 to May 6, 1991, the Cryogenic Infrared Radiance Instrumentation for Shuttle (CIRRIS 1A) measured spectral and spatial (“Earth limb scan”) distributions of the atmospheric infrared (IR) emissions using a Michelson interferometer. The IR spectral radiant emissions from the greenhouse gases were collected at a shuttle altitude of 260 km in the 9–13 μm atmosphere infrared window. Before and after the flight, the response of CIRRIS 1A to the IR spectral emission sources was calibrated using absolute and spectral source types. The Fast Atmospheric Signature Code 3, which used the HITRAN92 database and predetermined temperature-pressure profiles from the National Meteorological Center, was used in an onion-peeling routine to retrieve gas concentrations from absolutely calibrated spectral data (moderate resolution ∼1.0 cm−1). Vertical profiles of O3, HNO3, CFC-12, and CFC-11 are presented. An error analysis is presented to show the quality of the measured spectral data and the accuracy of these retrieval results. The concentrations of CFC-11 (3.0×10−4 ppmv) and CFC-12 (4.9×10−4 ppmv) in the tropopause region are consistent with a global flux increment rate of about 5% yr−1. The observed concentrations of HNO3 are consistent with previous reports for a relatively clean stratosphere.
