Stationary measurement and observation networks, such as the synoptic climatology network of the German Weather Service or the German federal states’ Measurement Network for Air Monitoring, were devised for purposes other than urban climatology and urban planning. In order to examine small-scale compositions and variations in climate or air conditions, specialized measurement and recording methods must therefore be developed.

As far as possible, measurement stations within existing networks should be utilized, since as a rule long-term data from these stations are already available, while the periods of measurement for special studies are usually limited. Thus it is possible to adapt temporary measurements to existing series of long-term measurements.
