The latest version of SMOKE, Version 2.1, has many updated features. It includes updated versions of BEIS3 and MOBILE6.2 for biogenic and on-road mobile emissions modeling, respectively. Both of these SMOKE features integrate predicted hourly meteorology to estimate hourly emissions fluxes from these emissions sources. The latest version also has support for polar stereographic output grids. Brief descriptions of the major steps in creating emissions files follow.
The first step in creating emissions files for input into CMAQ is to import the raw inventory data. The raw inventory data is usually in ASCII format. The SMOKE program Smkinven reads in this raw data and outputs an I/O API SMOKE intermediate inventory file.
