Abstract
The Clean Air Act Amendments of 1990 incorporated aggressive new regulations for emissions reductions. These limits were established to help reduce the impacts of air pollution on public health and sensitive ecosystems. Assessment of whether or not these emissions reductions rules are having their intended effects on atmospheric levels of pollutants requires the analysis of monitoring data in a manner that accounts for spatial structure issues in the data. Researchers developed a new technique for spatial interpolation of non-stationary processes. Under this approach, the field is represented locally as a stationary isotropic random field. However, the parameters of the stationary random field are allowed to vary across space. The interpolation strategy incorporates an expression for the spectral density at high frequencies.
