Funktionentheorie auf Holomorphiebereichen,, and CO.) are of special interest. The Institute of Atmospherics Physics has performed observations of these trace gases aboard different research aircraft for many years. In this chapter instrumental techniques used to measure these species are presented.

Chemical Composition of the Atmosphered particular attention. Therefore, research is now focused on the composition and processes in the upper troposphere and lower stratosphere, a key region in this respect. In this chapter the chemical composition of the atmosphere is addressed and selected examples of significant advances in this field are presented.

Thunderstorms: Trace Species Generatorster source in airborne field experiments accompanied with model simulations. The global lightning NO source is found to be distinctly larger than that from aircraft (factor ~5, uncertainty ~50–100 %). Lightning flashes in tropical regions seem to produce less NO per flash compared to other regions.

Long-Range Transport of Air Pollutantsl pollutants released by forest fires (e.g., soot). Also secondary pollutants (e.g., ozone) that are formed near the source region undergo transport. Recent advances in understanding atmospheric transport pathways, source-receptor relationships, and transformation of pollutants during transport are described.

Contrails: Visible Aviation Induced Climate Impactby a contrail varies strongly relative to the global mean, and may be positive or negative, depending on aircraft, route, solar and Earth-atmosphere parameters. Here we summarize present knowledge on contrails with respect to aviation and atmospheric research.

Chemical Ionization Mass Spectrometric Measurements of Atmospheric Trace Gases IPA. Sophisticated calibration techniques and in-flight calibration systems are developed to ensure high data quality. The CIMS instruments are employed preferably on research aircraft; in addition, observations are performed on ships, ground based sites and in laboratory scenarios including atmospheric chambers.
