| 18 | !! This software is a computer program whose purpose is to simulate the |
---|
| 19 | !! atmospheric gas phase and aerosol composition. The model is designed to be |
---|
| 20 | !! used within a transport model or a general circulation model. This version |
---|
| 21 | !! of INCA was designed to be coupled to the LMDz GCM. LMDz-INCA accounts |
---|
| 22 | !! for emissions, transport (resolved and sub-grid scale), photochemical |
---|
| 23 | !! transformations, and scavenging (dry deposition and washout) of chemical |
---|
| 24 | !! species and aerosols interactively in the GCM. Several versions of the INCA |
---|
| 25 | !! model are currently used depending on the envisaged applications with the |
---|
| 26 | !! chemistry-climate model. |

---|
| 65 | ! Method: |
---|
| 66 | ! |
---|
| 67 | ! Interpolation of the coefficients between those of seasalt and rural conditions |
---|
| 68 | ! depending on the composition of the aerosol. This approach seems justified, because |
---|
| 69 | ! the effect of RH on particle growth is much larger than that of the composition. |
