Abstract
The meteorology during the experiment performed on Kleiner Feldberg (Taunus) by the EUROTRAC subproject GCE during the period 27 October to 13 November 1990 is discussed. A general description of the synoptic situation and trajectories of the air masses reaching the observation site are presented. With the help of cloud-base observations and a stability analysis, an attempt is made to distinguish between periods with orographic and nonorographic clouds. For the different cloud episodes observed, the meteorological situation of each individual day is described with respect to cloud type, height of cloud-base, wind speed, wind direction, temperature and cloud liquid water content. Trace-gas measurements are used to attempt a qualitative analysis of pollution sources affecting the chemical observations at Kleiner Feldberg.
