Abstract The conclusions of a workgroup are presented outlining methods for processing meteorological data for use in air quality diffusion modeling. To incorporate the proper scaling parameters the discussion is structured in accordance with the current concepts for the idealized states of the planetary boundary layer. The authors recommend a number of models, the choice of which depends on the actual idealized state of the atmosphere. Several of the models characterize directly the crosswind integrated concentration at the surface, thus avoiding whenever justified the assumption of a Gaussian distribution of material in the vertical. The goal was to characterize the meteorological conditions affecting the diffusion for transport distances on the order of 10 km or less. Procedures are suggested for estimating the fundamental scaling parameters. For obtaining the meteorological data needed for estimating the scaling parameters, a minimum measurement program to be carried out at a mast is recommended. If only synoptic data are available, methods are presented for the determination of the scaling parameters. Also, methods are suggested for estimating the vertical profiles of wind velocity, temperature, and the variances of the vertical and lateral wind velocity fluctuations.
