Summary:

Mathematical pollute diffusion into atmosphere models utilization is connected with their accurateness and their notice capability, which is a function of their input parameters. Worldwide standards are fixed to the algorithms of parcial inputs with certain unification of typic sequences and empirical coefficients. Otherwise these guarantee results comparability in condition of describe phenomenon’s standardization; but simultaneously in “black box” models utilization, they do not respect the running processes individuality and their verification could be no-address to surface. Therefore it is necessary to know the detail structure and model algorithm, conditions of its utilization, boundaries accurateness and possible results diffusion as a function of accurateness inputs. This condition fulfils models recommended by EPA, in a condition of adequat inputs and for specific events are using “case by case” models with beforehand-defined conditions.
