  1. Input to the SAON Roadmapworkbasedonwork done in INTAROS whereobserving systems areassessedaccording to scientificthemesStein Sandven, NERSCMeeting 20 May 2019

  2. The broadscopeof Arctic observing (1) The SAON Roadmapshouldacknowledgethat Arctic observing (AO) is a complex system withseveraldimensions. Broadlyspeaking, AO is driven by theneed to support: • Scientific disciplines: atmosphere, ocean, cryopshere, terrestrialthemes • Societalbenefit areas: weather, climate, environment, naturalhazards, resources, economicactivities, + • Community-driven requirements: acrossseveralscientific and socialbenefit areas (2) Organisationof AO is complex: from localscale to global, from projects to largeprogrammes. In many cases AO is part of a global or larger-scale system, whichshould be recognised in the SAON Roadmap (3) What to observe: Essential variables aredefined to helpprioritize, basedon • Requirements to AO basedonobjectives (scientific, socialbenefit areas) • Existing and evolving AO activities, and • Identify gaps in the AO data products (4) Example: Ocean observing (next slides)

  3. Ocean observing: how it evolves, whoaretheactors, etc. Ocean observing is divided in sub-topics – eachwithspecificrequirements to observations: physicaloceanography, marine meteorology, tides and sealevel, marine biology and ecosystems, fisheries, support to shiptraffic and marine operations, pollutionmonitoring, etc. On largescale: • AO is linked to the global system (e.g. ARGO), withspecificlimitations in the Arctic • Overarchingbodies: GOOS under WMO/IOC, with regional subgroups (e.g. EuroGOOS) • National marine institutions (research, academia, governmentalagencies) arekeyplayers • European agencies and researchinfrastructures, basedmainlyonnationalcontributions On regional-localscale • Coastal states have responsibilities (EEZ, etc.) • Resource exploitation, foodproduction, etc. • Environmentalprotection • Marine traffic, safety, forecsting services • Observations to serve localcommunities

  4. Evolvingstrategies for oceanobserving The SAON Roadmapneed to be alignedwiththenumerousstrategies and implementation plans beingdeveloped for oceanobserving, e.g. • Oceanobs’19 is a keyeventwithseveralwhitepapers in preparation, alsoaddressing Arctic Observing • WMO workshop «Enhancingoceanobservations and research, and thefreeexchangeof data, to foster services for safetyoflife and property» in Geneva, Febuary 2019. https://public.wmo.int/en/events • European Ocean Observing System, EOOS Implementation Plan 2018-2022 (http://www.eoos-ocean.eu/eoos-strategy-and-implementation-plan-2018-2022-released/) • ESFRI Roadmap 2018 (http://roadmap2018.esfri.eu/), where ACTRIS, EPOS, Euro-ARGO are included, all with Arctic components • Copernicus requirements for Arctic observations (https://ec.europa.eu/jrc/en/publication/user-requirements-copernicus-polar-mission)
