Buildings with a positive TRACER Attribute are known as chemical emitters. Chemical emitters produce chemicals across their surface, which are then transported by flowing water.
Buildings with a negative TRACER Attribute are known as chemical decomposers. These act as scrubbers or decomposers by removing chemicals from the hydrological model.
In situations where water is absent, chemicals will not be moved between cells.
Notes
- Chemical emitters must be Buildings on the surface, not Buildings situated below the surface.
- Chemical emitters' attributes do not take the form of function values, and thus must be added manually or as part of loading in geodata.
- Chemicals have generic definitions, in terms of name and magnitude, to allow for the modeling of arbitrary tracers.
