| description | This study presents the analysis of the structure and air mass
characteristics of the lower atmosphere during the field campaign PARADE
(PArticles and RAdicals: Diel observations of the impact of urban and
biogenic Emissions) on Mount Kleiner Feldberg in southwestern Germany during
late summer 2011. We analysed measurements of meteorological variables
(temperature, moisture, pressure, wind speed and direction) from radio
soundings and of chemical tracers (carbon dioxide, ozone) from aircraft
measurements. We focus on the thermodynamic and dynamic properties that
control the chemical distribution of atmospheric constituents in the boundary
layer. We show that the evolution of tracer profiles of CO<sub>2</sub> and
O<sub>3</sub> indicate mixing across the inversion layer (or entrainment
zone). This finding is supported by the analysis of tracer–tracer
correlations which are indicative for mixing and the relation of tracer
profiles in relation to the evolution of the boundary layer height deduced
from radio soundings. The study shows the relevance of entrainment processes
for the lower troposphere in general and specifically that the tracer–tracer
correlation method can be used to identify mixing and irreversible exchange
processes across the inversion layer. |
