Other sections include matter, elements, the periodic table, reactions, and atoms. 5 the regional model Weather Research and Forecasting with Chemistry (WRF-Chem). However, the process may be inefficient if the soil has a high organic matter content. The air quality component of the model is fully consistent with the meteorological component; both components use the same transport scheme (mass and scalar preserving), the same grid (horizontal and vertical components), and the same physics schemes for subgrid-scale transport. Compiling WRF-CHEM on BG/L. An example of a dust forecast using WRF-Chem compared to MODIS satellite observations is shown in Figure 3. The version of WRF I used is WRF 3.
