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