Report from WP2: Months 1-6 Roberta Pirazzini, FMI (lead)

Report to EMDESK: Initial assessment of the data gaps, plans for organizing the gap analysis, initial listing of the sites and research groups to include in the discussion. To harmonize the collection of the information needed for the assessment and cataloguing of the existing Arctic in situ observing systems, in situ data collections, and satellite products, a survey composed by three questionnaires has been created. The survey capitalizes and advances the data assessment efforts done in previous and parallel projects (FP7 CORE-CLIMAX, H2020 GAIA-CLIM, H2020 EU-PolarNet), and it has received feedback from SAON.

Survey: A. The Arctic existing in situ observing systems Creation of 3 QUESTIONNAIRES, to collect the info needed TO ASSESS AND CATALOGUE : A. The Arctic existing in situ observing systems B. The in situ datasets: already established (Task 2.1), exploited (Task 2.2), and integrated into existing repositories (Task 2.3) C. The Arctic existing satellite products - The questionnaires will be web-based, open to all partners and collaborators through the INTAROS internal web page: http://intaros.nersc.no/node/125

Feedback to the survey from the INTAROS partners: It is not so clear who should fill questionnaire A For each of the listed observing systems, partners will be appointed on the basis of their experience. They can contact system managers if needed. In addition, all those who fill questionnaire B have the possibility to fill questionnaire A for the systems where their data collections belong to. The instructions are now (hopefully) more clear on this point The list of ECVs is incomplete/insufficient Right. What about using the list indicated in the Initial Requirement Report (D1.1)?

Feedback to the survey from the INTAROS partners: Added variables on the basis of D1.1: TERRESTRIAL, CRYOSPHERE: Glaciers (Area, elevation change, glacier mass change, glacier topography, surface radiation budget (longwave budget, shortwave budget, albedo), surface temperature). TERRESTRIAL, CRYOSPHERE: Snow (Spatial extent of snow, fractional snow cover (viewable and canopy adjusted), snow depth, snow water equivalent, snow grain size, snow impurity content (or radiative forcing by impurities)) TERRESTRIAL, ECOSYSTEMS: greenhouse gas fluxes (CO2, Methane) OCEANIC, PHYSICS: Sea-ice (sea ice concentration, sea-ice extent/edge, sea ice thickness, sea-ice drift, sea ice floe size, snow thickness, sea ice albedo) OCEANIC, BIOLOGY/ECOSYSTEMS: Primary production OCEANIC, BIOLOGY/ECOSYSTEMS: Secondary production OCEANIC, BIOLOGY/ECOSYSTEMS: Fish abundance and distribution OCEANIC, BIOLOGY/ECOSYSTEMS: Marine mammals and polar bears OCEANIC, BIOLOGY/ECOSYSTEMS: Marine biodiversity

Feedback to the survey from the INTAROS partners: Sections 2 and 4 of questionnaire C need to be adapted to satellite products The survey is too long (time consuming) for collaborators Should we ask collaborators to participate to the survey by invitation, or by opening the survey to the public? Should they access the whole survey, or only a simplified version of it? Should we let them to select, if they want to fill the full survey or a simplified version? Or only the obligatory fields of the survey? The simplified version of the survey could follow the Appendix A of the Data Management Plan V1 (D1.2)

Feedback from SAON: Avoid overlapping with EU-PolarNet We think that there is not much this risk, but we should collaborate to benefit from each other and optimize the use of resources The survey is very important and complementary to the ongoing initiatives in EU and US SAON will follow the outcomes of the survey very closely

Agenda for the WP2 discussion on 8th of June Illustration of the web versions of the questionnaires.  Questions to WP3 Leaders: do you see the need of mutual feedback between WP2 and WP3 concerning data management, metadata, etc., to harmonize the information that we are going to provide to WP5?  Discussion on the feedback to the survey Question to WP4 Leaders: would the questionnaires (or part of them) apply also to the citizen-collected data?  Question to Theme leaders: are the questionnaires suitable for your field?   Question to WP5 Leaders: do the questionnaires collect everything that is needed in WP5 to ingest the data into the iAOS? Question to WP1 Leaders: is there something that we should change/add in the questionnaires to assess if the observing systems or data meet the requirements addressed in WP1? Question to WP6 Leaders: do the questionnaires collect all the relevant information needed in WP6?  Question to WP7 Leaders: do you have comments on the layout of the web questionnaires?
