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