#27 Topic: Trace gas and aerosol remote sensing in the infrared spectral region
Lecturer: Justus Notholt
Date: Monday, May 8, 2023 10:00 – 11:00 a.m.

The ground based solar absorption spectrometry in the infrared spectral region using Fourier-Transform-Spectrometers has been established as a powerful tool for studying the composition of the atmosphere. About 20 trace gases can be retrieved, including some greenhouse gases, CFCs, trace gases involved in the stratospheric ozone chemistry, and several tropospheric pollutants. Besides absorption measurements emission studies can be performed, yielding in addition to the trace gas results aerosol properties. During the talk the basics of the Fourier-Transform-Spectrosopcy will be discussed together with some results of our measurements within (AC)³.
