2   Data Exchanged with Component Models

This section provides a list of the states and fluxes exchanged between the Flux Coupler an each component model. Each component model exchanges data with the Coupler only. Component models have no direct connection with each other -- all data is routed through the Coupler. All data is in the form of 2D fields (on latitude/longitude grids), except runoff data, which consists of an array of drainage basins, and certain timing and control information, which consists of scalar real or integer values (e.g. the current simulation data and time, and parameters specifying the solar orbit). box diagram

Each component model provides the Flux Coupler with a set of output fields. Output fields from a model include output states (which can be used by another component to do a flux calculation) and output fluxes (fluxes that were computed within the model and which need to be disseminated to other component models).

The Coupler provides each component model with input fields. Input fields sent to a model include input states (the state variables of other models, which are needed to do a flux calculation) and input fluxes (to be used as forcing fields).
