The document describes procedures for the measurement of emissions from diffuse sources. The determination of emissions from diffuse sources is based on the determination of measurance such as substance concentrations and meteorological parameters and is combined, where appropriate, with a calculation model. Measurements at diffuse sources are carried out in the interface to the atmosphere or after the pollutants to be measured have entered the atmosphere.
