Major model properties.

Model capability Scale
WRF-SFIRE-CHEM Level set fireline;
Atmospheric physics and chemistry, smoke transport and gaseous products;
WRF’s nesting.		 Spatial scale: regional and local;
Domain: km or larger;
Fire grid spacing: tens of m.
WFDS and FIRETEC Emphasis on capturing the fire behavior;
Relatively near-field smoke plume rise and downwind transport;
Simple atmospheric physics.		 Spatial scale: local;
Domain: about 1 km, larger for WFDS-LS.
Grid spacing: WFDS-PB: Grid of cm ∼ m (WFDS-PB), m (FIRETEC), m or larger (WFDS-LS).
Daysmoke and PB-P Computationally fast with simple physics;
Topography-air interaction for night smoke.		 Spatial scale: local;
Domain: ∼ 5 km (Daysmoke), 1 km (PB-P);
Grid spacing: ∼ 100 m.
CMAQ-BlueSky 3D Eulerian photochemical transport;
Gas, aerosol, and aqueous phase chemistry;
Air quality (especially PM and ozone).		 Spatial scale: regional;
Domain: up to 1000s of km;
Grid spacing: 4∼12 km (1 km for fine scale applications).
