The management (MAN) and user interface (INT) sub-projects span the project as a whole, and will interact with each of the other sub-projects and with each other, to ensure effective management of the project and effective comminications with users, across the range of MACC-II's activities.

The principal elements of the input cluster are the observational data acquisition (OBS), general emissions (EMI) and fire data assilation (FIR) dub-projects, although retrieval work located within GHG, GRG and AER for reasons of effective management can also be regarded as as part of the observational pre-processing work within a more general input-data cluster.  In addition, some of the input data for validation activities will be acquired directly by participants in the validation (VAL) and by those in other sub-projects that carry out some of their own validation.  The solar radiation (RAD) sub-project also entails a quite considerable direct acquisition and processing of observational data.

The global data analysis and forecasting functions will be carried out in the cluster of global sub-projects: greenhouse gases (GHG), reactive gases (GRG), aerosols (AER) and integrated data assimilation, production and service (GDA).  Development work in data assimilation and modelling will be performed in GHG, GRG and AER, and running of the integrated system will be undertaken in GDA.  These sub-projects involve multiple interactions with each other, reflecting in part the various chemical and physical interactions that take place within the atmosphere.  GHG, GRG and AER will also provide supplementary product lines and services based on the outputs of the global data assimilation and forecasting.

The cluster of global sub-projects will also interact with the principal sub-projects providing input observational and processed emissions data (OBS, EMI, FIR), and the the regional sub-projects on ensemble forecasting (ENS) and validated assessments (EVA) for the European domain, which will be recipients of the boundary data provided by global production.  Interaction with the regional data assimilation development sub-project (EDA) will involve exchange of information on such topics as the assimilation of satellite data on atmospheric composition and the variational estimation of emissions.  There will also be interaction between elements of the global cluster and the RAD sub-project, as RAD will undertake assessment of the UV fields provided by the global cluster and is a user of fields such as aerosol from the global system.

The cross-cutting VAL sub-project will also interact heavily with the global cluster  as its main focus is on global products, although it will link also with assessment of the regional forecasts, and will provide feedback to FIR nad EMI as to the inferred deficiences of the inputs they provide to the global modelling. FIR nad EMI will also link with GHG and AER in view of the work on surface flux-inversion to be acrried out in the global sub-projects.

The core components of the regional analysis and forecasting cluster are EDA, ENS and EVA.  These sub-projects have a strong link to the European-policy support sub-project (POL). In addition, the products of RAD have a strong focus on Europe and its immediate surrounds.  These five sub-projects can thus be regarded as forming a broader cluster delivering products for the European domain.

The formal management structure of MACC-II is quite flat, with high-level management positions defined only at project and sub-project levels, as set out in section B2.  The management structure does not involve formal definition of clusters or cluster leaders.  Clusters of sub-projects will netertheless meet from time to time, as will clusters of sub-project managers, under designated leaders or co-leaders.  For these meetings, cluster definitions may vary depending on the main topics to be addressed.  This arrangement follows that which has proved to be effective in MACC.
