Work carried out included:
• An assessment report on a ‘system-of-systems’ approach for assigning suitability of candidate non-satellite measurements for satellite calibration and validation, followed by its application to a broad range of candidate measurement networks and the collection of associated metadata.
• Development of a 3D-discovery tool for metadata from ground-based observing networks.
• Model and statistically-based studies to quantifying the impacts of geographical gaps in in-situ observational capabilities.
• The construction of traceability chains and ‘product traceability and uncertainty documents’ for various non-satellite instrument types as a first step towards full instrument characterisation.
• Modelling and statistically-based analysis describing generic metrology aspects of an atmospheric measurement and of data comparisons.
• Libraries of climatological co-location uncertainties, containing guiding material and look-up tables.
• A completed assessment of new satellite missions with respect to global NWP systems (GCOM-W AMSR-2, FY-3C, F-19 SSMIS, TVZA-GY microwave imager/sounder on the Russian Meteor-M N2 satellite, and GPM GMI).
• The ‘GRUAN processor’, which converts radiosonde profiles and their uncertainty to TOA radiance equivalent measurements, and subsequent efforts to monitor reference data (from GRUAN) with respect to global NWP fields.
• Report detailing approach to the calibration and validation of (atmospheric state variable) EO data, and detailing proposed approach to other ECVs and associated EO data
• Development of the 'Virtual Observatory' demonstrator tool, based on user requirements derived from a user survey and the feedback of two user workshops with external users, as well as the series of ‘Roadshow’ events at target user institutions.
• Production of five official releases of a Gaps Assessment and Impacts Document (GAID), including an online searchable catalogue of gaps and SMART remedies.
• Formulation of eleven high-level recommendations resulting from the gap analysis.
As a member of the Open Data Pilot, where possible, these activities have been developed in a way that enables sustainability, exploitation, and potential future development by project partners or third parties.
Principal outcomes have been collated together and are presented at

Substantial efforts were made to engage the user community throughout the project. Presentations were made at relevant conferences and workshops, there were two user workshops and, in the final year, a series of ‘Roadshow events’ addressed key stakeholders.
