Division 3 SERVICE ARCHITECTURE

The design of the service architecture shall ensure consistency with the overall vision and development strategy of Copernicus.

There shall be four main service elements:

1. (a)

   acquisition and pre-processing of input data, primarily observations (from both satellite and in-situ instruments) and ancillary data that are needed to estimate emissions of pollutants and to assess concentrations of pollutants in the atmosphere;

2. (b)

   global processing: shall be operated in three modes to deliver the products required by the users:

   1. (1)

      daily production for near-real-time analyses and forecast;

   2. (2)

      daily production for delayed-mode analyses and forecast;

   3. (3)

      re-analyses production stream providing multi-annual consistent datasets with a frozen model/assimilation system;

3. (c)

   regional processing: shall be covered with a higher spatial resolution and shall support in particular further downstream modelling activities for sub-regions at even finer scale as well as air quality and pollen monitoring and forecasting national activities;

4. (d)

   supplementary services: shall be relative to applications processing, services and products that are built on top of or integrated into the main global and Union regional processing outputs.

The four cross-cutting functions shall deal with the following:

1. (a)

   quality control and assurance;

2. (b)

   archiving;

3. (c)

   product dissemination;

4. (d)

   user interaction, training and outreach.
