This guideline describes how to collect, to analyze, and to present local climate with the help of mobile measuring systems in an adequate and assured manner. The guideline describes the measurements with mobile carriers (cars, bicycles, trolleys, and backpacks), because they allow a highly differentiated analysis of small regions. Aim of these investigations are the regional distributions of the relevant climatic variables: air temperature at fixed daily or yearly time, air humidity, streaming, solar and terrestrial radiation, deduced parameters like mugginess or other bioclimatic factors, assignment of areas with uniform microclimatic shape (climatotope).
