ABSTRACT

Comprehensive atmospheric composition studies require multi-scale numerical
experiments to be carried out, which to clarify to some extend different scale processes
interaction, but also to further specify requirements for input data (emissions, boundary
conditions, large scale forcing). Model interfaces from synoptic trough meso- to local
scale have to be tailored. Shortly speaking, extensive sensitivity studies have to be
carried out, tailoring the model set-up and parameters – a possible forerunner of single
model ensemble forecasts.

Performing extensive simulations of this kind with up to date highly sophisticated
numerical models obviously requires computer resources of the order of magnitude of
those provided by the so-called supercomputers. Using supercomputers, however, is
rather expensive and far beyond what most of the research groups can afford. Luckily
an alternative technology – the grid computing, is recently very intensively developing,
which makes it already quite relevant to formulating and solving problems absolutely
unthinkable several years ago.

Some examples of environmental problems which are recently developed / tested /
treated as grid applications are given in the present paper.
