Report on the enhancement of CNR IMAA atmospheric observatory for the provision of RIs integrated and synergistic data products

This deliverable is prepared in the context of the ITINERIS project, within the Work Package 4 that deals with the integration of Research Infrastructures (RIs) working in the atmospheric domain through synergistic approaches and cross boundaries developments. Its main aim is to report the progress in the enhancement of the CNR-IMAA atmospheric observatory (CIAO) which was carried out by operating on multiple fronts: from a significant straightening of its observational capability of aerosol, clouds and trace gases with the aim of providing high quality data and integrated data products, to the enhancement of the CNR-IMAA connectivity for guarantying a stable, fast and protected connection of all the instruments to the respective European RI but also to the digital resources that are being developed in ITINERIS like the Virtual Research Environment (VRE) and the ITINERIS HUB.
