Lecture content:
Many atmospheric trace gases have spectral lines in the infrared, making this region suitable for the detection of the atmospheric composition. Beside the total column concentrations the spectral line shape of the lines often allows to retrieve their concentration profiles. Measurements in the infrared require high resolution instruments, whoose instrumental line shape is well known. Furthermore, due to the low intensities, these instruments require to have a high light throughput. For several decades now interferometers have been found to be suitable for the spectroscopy in the infrared. In this lecture the basics of interferometers will be discussed together with a few examples on their use in atmospheric studies.
