Abstract
This paper illustrates inhomogeneities in pollutant time-series data caused by changes in data reporting practices. These inhomogeneities may have a substantial effect on trend assessments. Therefore, in estimating trends or mean levels in pollutant time series or attributing changes in pollutant levels to an emission control policy, it is important to homogenize time-series data.
