Abstract |
This document provides a technical description, user's guide and program listing for (1) STRAM - a variable trajectory, reactive plume-segment model for ground level air pollution assessments resulting from multi-source emissions on a multi-state scale, and (2) a supporting program, Random-to-Grid, which generates gridded wind data for STRAM from synoptic wind data at arbitrarily located observing stations. The reactive plume chemistry is calculated by a Subroutine STRAC and related subroutines, which calculate the diffusion, the wet and dry depletion, and the reactive chemistry within each plume segment. The principal output of STRAM is concentrations on the sampling grid and at each particularly specified sampling point for each of the analyzed chemical components. These are available for three averaging periods (1) once for the entire running time, (2) serially for the basic sampling interval, and (3) serially for an arbitrarily specified intermediate time. Matrices of maximum values over all matrices of this last type are also printed out. |
