Abstract

During the night from May 17 to May 18, 1989, the first of four flights of the Michelson Interferometer for Passive Atmospheric Sounding, Balloon-borne version (MIPAS-B) instrument took place from the Centre National d'Etudes Spatiales balloon-launching site at Aire-sur-l'Adour (France, 44° N latitude). From approximately 33 km float altitude, stratospheric and tropospheric limb infrared emission spectra have been recorded by this novel type of fast-scanning interferometer. Although the measured spectra did not reach the expected quality and the a priori information on the corresponding viewing directions was coarse, the data were processed successfully with a retrieval algorithm specially adapted for application to noisydata. Mixingratio profiles of ozone, nitric acid, CFC-11, and CFC-12 havebeen retrieved from limb sequences of wide spectral intervals by nonlinear least-squares fitting in combination with a layer-bylayer onion-peeling approach. A rigorous error analysis has been carried out by means of Monte Carlo calculations.

摘要

1989年5月17日夜间至5月18日，迈克尔逊被动大气探测干涉仪气球搭载版（MIPAS - B）进行了四次飞行中的首次飞行，从位于阿杜尔河畔艾尔（法国，北纬44°）的国家空间研究中心气球发射场升空。在约33千米的浮空高度上，这种新型快速扫描干涉仪记录了平流层和对流层边缘的红外发射光谱。尽管测量光谱未达到预期质量，且相应观测方向的先验信息粗略，但利用专门适用于噪声数据的反演算法成功处理了这些数据。通过非线性最小二乘法拟合并结合逐层剥洋葱法，从宽光谱区间的边缘序列中反演了臭氧、硝酸、氟利昂 - 11和氟利昂 - 12的混合比剖面。借助蒙特卡罗计算进行了严格的误差分析。
