TW2018, 13-14 Sept 2018 2 WGISS Carbon Community Portal CEOS Work Plan 2018-20 - CARB-15: Carbon Data Portal prototype (WGISS Action) Objective: Implement a prototype carbon data portal to facilitate the discoverability and accessibility of ECV products and space-borne CDRs. The portal will seamlessly access data both in CWIC and FedEO to provide necessary data and services to the carbon science community of both CEOS and GEOSS. Approach: prototype developed by WGISS in coordination with CEOS WGClimate Carbon represpesative (requirements and use cases provision/validation). Status: Several iterations held between WGISS and Carbon teams. Carbon Portal latest version (August 2018) with Carbon Team for review/feedback. Next steps: 1) Improve discoverability of ECV/CDR key datasets for Carbon Community and functionalities based on received feedback; 2) Open-up portal to wider user community to gather additional feedback (target end October 2018).

Facilitate the completion and follow-on activities of the AC-VC whitepaper on defining an optimum constellation for CO2 and GHG monitoring, including the joint competences of CEOS and CGMS, and in

the general framework of the continued implementation of the CEOS Carbon Strategy 2. Advance the relationship with CGMS for an operationally implemented and sustained observation capability. Consider establishing a formal working relationship between CEOS and CGMS as with the successful ongoing relationship on Systematic Observations of ECVs in support of UNFCCC. 3. Place the space segment in the broader context of a fully sustained system for CO2 monitoring. Individual CEOS Agencies have counterparts in their individual countries/regions who have responsibility for Inventories, the required modelling, in-situ infrastructure and the ground segment elements. 10 COP-23/SBSTA-47 Considerable support in the RSO negotiations from Japan and EU deleg Especially for Conclusions 9 & 12 11 CEOS CGMS Coordination on GHG monitoring - options 1. Continue adhoc collaboration in context of CEOS Carbon Strategy Actions e.g. as-in joint efforts on AC-VC

Whitepaper 2. Establish a sub-group (with dedicated resources) in context of existing standing WG i.e. Joint WG on Climate 3. Extend the current CEOS Atmospheric Composition Virtual Constellation to be a Joint CEOS-CGMS Virtual Constellation 4. Establish a dedicated Joint WG specifically on Carbon /GHG observations Assess/discuss these different options both within CEOS and CGMS - propose a preferred option 12 Pros and Cons of Options 2 & 3 Option 2 Option 3 Subgroup to Joint Joint AC-VC WGClimate Pros The Joint CEOS-CGMS WGClimate already exists, just need to decide on assigning subgroup lead maybe update ToR Existing and strong working relationship with GCOS and UNFCCC/SBSTA

May provide basis for longer-term home for CEOS Carbon Strategy Action Could build on existing adhoc collaboration started in context of GHG Whitepaper If focus is primarily on building physical constellation, based on GHG Whitepaper, then competence are within VC Would provide an additional model of collaboration between CEOS and CGMS GHG may not be only area of CEOS-CGMS collaboration within AC-VC e.g. Air Quality Will Ensure that the GHG products requirements/improvement process follows same being implemented for other ECVs/CDRs Take advantage of other ECVs associated to the natural Carbon Cycle Cons Enlarges scope/mandate of WGClimate Would need dedicted resources competences for CEOS agencies to WGClimate Would need strong dialogue between

WGClimate and AC-VC Concern on creating parallel track with SBSTA and GCOS Risks to remain disconnected to13other activities of CEOS Carbon Strategy Conclusion from CGMS-46 CGMS was requested to confirm its interest in pursuing a more structured collaboration with CEOS on GHG monitoring and provide comments or preferences on the options presented. In the discussion it was noted that whilst recognising the technical capabilities of the CEOS AC-VC team and the support it is providing in terms of drafting the White Paper, concerns were raised by several members that it may not be the most suitable entity to lead activities with strategic implications and reporting to various bodies like UNFCCC and SBSTA. It was also noted that JWG Climate has domstrated its ability to take on board complex and heavy tasks and deliver on schedule. Furthermore JWGClimate already has all the reporting lines in place. Whilst having concerns on the workload it was noted that the situation is now improving. The CGMS Plenary then decided on the following Action: Action: JWGClimate to complete their analysis of the feasibility of establishing a subgroup on CO2/GHG in JWG Climate 14

Recommendation: CGMS to recommend to the CEOS Chair the Possible Hybrid Scenario Option 2 WMO IG3IS GEO Carbon & GHG GCOS/UNFCCC Initiatives on Carbon relevant ECVs, input for SBSTA Reporting SBSTA, formal GCOS link Space Agency input to GEO Initiative Joint WGClimate Addressing

Atmospheric Domain CGMS representatio n Conclusions Conclusion There is an increasingly strong policy demand for coordinated provision of information on GHGs (both from UNFCCC/SBSTA and GCOS) This has strong synergies with the successful existing collaboration between CEOS and CGMS on more traditional Systematic Observations (ECVs, CDRs) The adhoc collaboration between CEOS and CGMS agencies in preparing the draft whitepaper on the GHG Constellation has proved to be effective, and brought complimentary competences to the existing team A number of options are available for a more structured collaboration on GHG monitoring, taking advantage of existing CEOS (and CGMS entities) of these would result in considerable added-value. Asked to Plenary for Decision 1. Confirm the interest in pursuing a structured collaboration between CEOS and CGMS in the area

Greenhouse Gas observations and monitoring 2. Confirm that the options considered for this collaboration, present, are representative of those available through the technical entities within the organisations 3. Agree that the identified proposed solution is appropriate, and that the implications of it's implementation are understood and acceptable (including those relating to resourcing and Agency participation) 4. Agree that the proposed timeline for implementation are appropriate and that the draft 17
