Abstract

Infrared radiometry and spectroscopy provide information related to many important problems of the upper atmosphere, such as specification of the radiative terms in the energy balance, composition of the atmosphere and transport of chemical species, and the chemical reactions producing the ozone balance. For studies of the stratosphere and higher layers, observations usually must be made above the troposphere; aircraft often are suitable platforms because of their large load carrying capacity, comparatively benign environment, and ability to operate easily at remote locations. Radiometry is useful chiefly in studying radiative energy balance and in measuring constituents, such as water vapor and ozone, which have strong bands with little interference from other molecules. Absorption spectroscopy, with the sun as a source, or emission spectroscopy, using radiation emitted by the atmosphere itself, may be used to detect and measure chemical species with concentrations less than one part per billion. Grating spectrometers and interferometric spectrometers have been used for both emission and absorption spectroscopy. Measurements have been made throughout the infrared. Techniques used for spectroscopy and radiometry from aircraft are discussed and some typical results by various observers are presented to illustrate the range of data which may be obtained.
