The sensitivity of a 3-dimensional Eulerian model to uncertainties in emissions and dry deposition velocities

Abstract

A 3-dimensional STEM-I Eulerian, regional scale transport/chemistry model for SO2 and sulfate is used to investigate the relationships between model predictions and the resolution and uncertainty in the emissions and dry deposition velocities. Model results for conditions of 4 July 1974 where the emissions are time modulated, where the emissions are increased and decreased, and where the dry deposition velocities are increased and decreased are presented and discussed. © 1986.
