Abstract

FLADIS is an extendable software system for displaying temporal and spatial distributions of concentrations of pollutants such as SC^, NC^, NO, particles, and O] (measured half-hourly or hourly) over whole areas. With the help of integrated statistical models deposition of dust constituents can also be displayed over an area. FLADIS consists of interpolation methods together with a dispersion or a statistical model. The interpolation is carried out by various methods such as, for example, Shepard, triangulation, and thin plate spline. The interpolation methods available can be expanded as needed through an interface for DLLs (dynamic link library). In the same manner, any available appropriate dispersion model or statistical model can be integrated into FLADIS. As output FLADIS cal
