The five meteorology files that SMOKE needs for biogenic emissions adjustments, calculation of on-road mobile source emission, and plume rise calculations are GRID_CRO_2D, GRID_CRO_3D, MET_CRO_2D, MET_CRO_3D, and MET_DOT_3D. The files are usually based on MM5 data, but must be specially formatted by a postprocessor like MCIP or MCPL.
The METLIST file is used to provide the file names of available meteorology files to the Tmpbio and Premobl programs. Premobl runs once for the entire modeling episode, and therefore needs all of the files at one time. If Tmpbio is being run for a period longer than the individual meteorology files, the METLIST file is used to combine multiple meteorology files so that Tmpbio can find the data it needs. The meteorology files provided to Premobl and Tmpbio must cover the desired episode and contain the requested variables. In the default SMOKE scripts, this file is generated automatically. The format of this file is shown in Table 8.73, “Format for METLIST”.
