Development of Mesoscale Air Quality Simulation Models. Volume 4. User's Guide to MESOGRID (Mesoscale Grid) Model

摘要

MESOGRID is a regional-scale grid model, based on the Egan-Mahoney method of moments, especially designed to simulate the air quality impacts of multiple sources at long transport distances. Highly user-oriented, MESOGRID provides a range of flexible options, and its clean, modular structure permits further modifications with ease. It is designed to be driven by user-specified meteorological scenarios, of arbitrary duration, constructed by a suitable meteorological preprocessor model (e.g., MESOPAC). It outputs spatially-gridded concentration arrays averaged over arbitrary time intervals of one hour or more, and is designed to be coupled to a postprocessor model (e.g., MESOFILE) to provide additional graphical and statistical analyses. Routines are provided for: plume rise; fumigation; linear conversion of SO2 to SO4; and dry deposition of SO2 and SO4.
