All MACC products related to atmospheric composition are made publicly available in accord with Copernicus data policy. Retrospective meteorological products from MACC’s reanalysis activities are also made publicly available.
The products comprise reports, graphical displays and datasets. The extent of the graphical displays is limited by the capabilities and capacities of the technical infrastructure to which MACC has access, but adjustments to the graphical products may be made within these constraints in response to user feedback. Data dissemination mechanisms established for routine supply of meteorological data are to be introduced as required, and may be more suitable than the initial web-based downloading facility for downstream-service providers who need to acquire data on a regular basis, especially for automatic processing. In addition to the comprehensive sets of MACC data supplied following GMES data policy, additional supporting meteorological data may be supplied to intermediate users so as to enable them best to serve their end-user communities. This supply is subject to assessment of requirements and the development of data policy.
