A parallel algorithm for an implementation of EUROS (EURopean Operational Smog) model on high-performance parallel computer platforms is presented. The atmospheric model system of partial differential equations is solved using the operator splitting technique. The parallel version of EUROS is based on an algorithm very closed to the well-known domain decomposition approach in numerical mathematics. Different decomposition of the model domain is used for the different submodels included in EUROS model. A grid refinement procedure, up to four levels in user defined subareas, leads to some difficulties in load balancing, which are discussed in the paper. The parallel algorithm reported can be used on (i) distributed memory parallel computers, (ii) parallel computers with shared memory and (iii) SMP computers.
