Abstract

This final report is concerned with tropospheric trace gas measurements by Tunable Diode Laser Spectroscopy (TDLAS). A TDLAS instrument was built which simultaneously measures four selected trace gases and is sufficiently sensitive for use in 'clean' air conditions. The instrument is the first of its kind to be used for measurements aboard ship platforms in clean marine air. In order to guarantee that the instrument function continuously for several weeks at a time under the difficult conditions encountered at sea, a variety of innovative technical developments were necessary. The TDLAS instrument was used to investigate boundary layer tropospheric chemistry in one engineering test and four field campaigns. Three of the field campaigns took place on board the German research vessels. The measurements on board the research vessels enabled different types of tropospheric air to be investigated: (i) clean maritime air; (ii) maritime regions influenced by continental sources of trace gases and pollutants, in particular the coastal region around the west coast of Africa was thoroughly investigated under downwind conditions. A large set of data of simultaneous measurements of key tropospheric trace gases (NO{sub 2}, CO, HCHO, H{sub 2}O{sub 2} and O{sub 3}) were obtained which help paint a more complete  More>>

The first measurements of H{sub 2}O{sub 2} in the remote marine boundary layer are reported. In selected regions successful TDLAS measurements of HCl and COS were obtained, results in themselves of importance. Intercomparisons of TDLAS and other measurement techniques were successfully undertaken. (orig./BBR).}
