The STEM-2K3 is a regional chemical transport model, with the
SAPRC99 mechanism (218 reactions), and all of the 30 photolysis
rates are explicitly computed through its on-line TUV.
Aerosol Ions are calculated by the on-line four-bin SCAPE II module, developed by
CalTech and UC-Irvine. This page includes 5-layer horizontal plots of STEM-2K3 Forecasts
over Northeastern USA in 12km horizontal resolution, which is nested within the
STEM Forecast over North America.
You can also view time-series or cross-section plots over any model grid.
