| 26 | !! This software is a computer program whose purpose is to simulate the |
---|
| 27 | !! atmospheric gas phase and aerosol composition. The model is designed to be |
---|
| 28 | !! used within a transport model or a general circulation model. This version |
---|
| 29 | !! of INCA was designed to be coupled to the LMDz GCM. LMDz-INCA accounts |
---|
| 30 | !! for emissions, transport (resolved and sub-grid scale), photochemical |
---|
| 31 | !! transformations, and scavenging (dry deposition and washout) of chemical |
---|
| 32 | !! species and aerosols interactively in the GCM. Several versions of the INCA |
---|
| 33 | !! model are currently used depending on the envisaged applications with the |
---|
| 34 | !! chemistry-climate model. |
