NCEO's NPG activity delivers expert scientific, technical and operational advice on EO-related policies and services to government departments and agencies. NCEO works particularly with the UK Space Agency and Defra, with a growing liaison with BEIS Climate Team. Advice covers scientific and technical insight; appraisal and review, reports; organisation of technical working groups and science surveys; and inputs to statements. Our expected activities are to provide: 1. Advice by the NCEO Director and senior staff to the UK Space Agency regarding UK Space Policy, including the subscriptions to European Space Agency programmes, Industrial Strategy and spectrum usage. 2. Advice to the Defra group, including Chief Scientific Advisor's Innovation programme regarding the application of space-based Earth Observation to environmental policy and services, including advice on the EU Copernicus programme, the Defra EO Centre of Excellence and the emerging UK Government Earth Observation Service. 3. Ad hoc advice to other government departments and agencies regarding the suitability of EO for particular applications and ways of overcoming particular challenges (e.g. supply of analysis ready data, utility of data cubes), for example to the BEIS Climate Team. 4. Coordination of advice to UK government (Defra, UK Space Agency) and technical expert activities related to the international Group on Earth Observations (GEO) and the Committee on Earth Observation Satellites (CEOS), including high level briefings. The aim is that UK organisations can contribute to and benefit strongly from developments in the international community, a current government priority. Societal and public benefit are important drivers for these global engagements.
