Transport of trace gases from the Upper Rhine valley to a mountain site in the northern Black Forest
Abstract
Measurements of meteorological parameters and trace gas concentrations from the Rhine valley to a summit of the northern Black Forest indicated the existence of a well developed upslope wind system during daytime. The behaviour of the time series of the CO volume fraction along the slope proves that the upslope winds accomplished a transport of polluted air masses from the Rhine valley to the summit. Correlations of O3 with CO volume fractions changed within a distance of about 10 km from a negative correlation in the valley to a positive correlation at the summit.
