Also shown are the associated CALGRID photochemical model, the KSP particle model, and mesoscale meteorological models that may include MM5/MM4, NAM(Eta), WRF, RUC, RAMS, TAPM and 1-10 Figure 1-2: Meteorological Modeling : CALMET Modeling flow 1-15 Figure 1-3: Dispersion Modeling : CALPUFF Modeling flow 1-16 Figure 1-4: Postprocessing: PRTMET postprocessing flow 1-17 Figure 1-5: Postprocessing: CALPOST postprocessing flow 1-18 Figure 1-6: Flow diagram of the diagnostic wind model in CALMET.

6 Winds derived from mesoscale models MM4/MM5, NAM(Eta), WRF, RUC, RAMS, TAPM or CSUMM can be introduced as the initial guess field A, or the Step 1 field B. Mesoscale model wind data (except CSUMM) can also be treated as observations C. Path A is 1-20 Figure 2-1: Processing Geophysical 2-2 Figure 2-2: Spatial coverage of each GTOPO30 tiles (files).. 2-5 Figure 7-1: MM5 horizontal grid (Arakawa B-grid) showing the staggering of the dot (.) and cross (x) grid points. The smaller inner box is a representative mesh staggering for a 3:1 coarse-grid distance to fine-grid distance ratio (from NCAR, 1998).. 7-7 Figure 7-2: Schematic representation of the vertical structure used in MM5. The example is for 15 vertical layers.
