Atmospheric emission spectra in the 700-2800-cm(-1) region have been measured from an aircraft at 9.45-11.89-km altitudes. All measurements were made viewing at the zenith at a spectral resolution of 2 cm(-1). The measurements were obtained using interferometer spectrometers, and the atmospheric radiation was modulated with a liquid nitrogen cooled chopper that eliminated the thermal emission of the spectrometers from the measured spectra. Essentially all the features of the spectra can be identified with known constituents of the atmosphere. The comparison with a theoretical emission calculation using a tropical atmospheric model was satisfactory except for the H(2)O that showed a smaller concentration by a factor of 5 than was assumed in the model at these altitudes.
在700 - 2800厘米⁻¹区域的大气发射光谱是从9.45 - 11.89千米高度的飞机上测量得到的。所有测量都是在天顶方向以2厘米⁻¹的光谱分辨率进行的。测量使用干涉仪光谱仪进行，并且用液氮冷却斩波器对大气辐射进行调制，从而从测量光谱中消除光谱仪的热发射。基本上光谱的所有特征都可以与大气中的已知成分相对应。与使用热带大气模型进行的理论发射计算相比，除了水的浓度在这些高度上比模型假设的小5倍外，结果令人满意。
