4.1.1 Stationary
Measurements
In areas with a pronounced topography such as
that frequently occurring in southern Germany, the appearance of
small-scale climatic variations requires a relatively dense
measurement network. The climatic elements of air temperature,
humidity, wind direction and velocity, and precipitation are
usually of primary interest, and are supplemented where needed
by measurements of air pollution.
Corresponding to the strong decline in SO2-emissions
in recent years, the air pollutants nitrogen dioxide, benzene,
soot, and fine particulate matter have gained importance, while
ozone as a large-scale problem does not have any direct
significance for urban planning. In order to translate point
measurements into statements for areas of land, it is necessary
to use numerical interpolation processes (s.a. Chapter
4.3.1). As a rule, the duration of measurement should span
one year, so that all seasonal variations can be recorded.
Orientation measurements (e.g. of cold air flows) can be of
shorter duration when necessary.
