Town hall 1: Introduction to YMC (Years of the Maritime Continent) and program 1 of WPOS (Strategic Priority Research Program of the Chinese Academy of Sciences) (Introduction to YMC and WPOS)
The townhall session is expected to coordinate planned research as well as identify gaps of Years of the Maritime Continent (YMC) and program 1 of the Strategic Priority Research Program of the Chinese Academy of Sciences (Western Pacific Ocean System: Structure, Dynamics and Consequence, WPOS). The aim of YMC is observing the weather-climate system of the Earth’s largest archipelago to improve understanding and prediction of its local variability and global impact.
The science themes of YMC include atmospheric convection, ocean and air-sea interaction, stratosphere-troposphere interaction, aerosol, and prediction improvement. These themes of YMC address the concerns and important issues of CLIVAR. In the tropical Western Pacific, the program 1 of WPOS has been aiming to achieve creative breakthroughs on the three-dimensional structures, characteristics and dynamic mechanisms of the variabilities of the major currents, as well as the feedback mechanisms of the Warm Pool to the East Asian climate since 2013. The objective of the session is to review and discuss the research progress featuring new findings during the execution of YMC and WPOS.

Town hall 3: PAGES Town Hall meeting
The PAGES (Past Global Changes) project (http://www.pastglobalchanges.org/about/general-overview) invites you to discuss common questions among the paleo, present day and future climate communities with the objective to strengthen the linkages between ongoing research in WCRP and PAGES.
PAGES is a core project of Future Earth and a scientific partner of WCRP that addresses observations, reconstructions and mechanisms of paleoenvironmental variations. PAGES deals with the physical climate system, biogeochemical cycles, ecosystem processes, biodiversity, and human dimensions, on different time scales - Pleistocene, Holocene, last millennium and the recent past. The meeting will explore how scientists working on long and short time scales (past-present-future) might interact more effectively to tackle some of WCRP’s Grand Challenges and CLIVAR research foci and benefit from common model simulations, data synthesis and methodologies.
The meeting will be organized with short presentations:
- PAGES and the WCRP/PAGES collaboration
- The status of the PMIP4 project
- Results and ongoing activity of some of the relevant PAGES working groups
- Attendee are invited to bring a one-slide presentation on their favorite subject to stimulate the discussion
Among many potential themes, we anticipate interactions on the following topics: long-term ocean variability, linkages between the hydrological cycle, climate trends and variability, the characterization and analyses of extreme events, and emerging constraints from the past that can contribute to assess the credibility of future projections.
In order to have a stimulating and efficient meeting, please send your expression of interest to Marie-France Loutre and Pascale Braconnot with a few key words indicating which subjects you would like to discuss, so that the final agenda will best reflect the interest and goals of participants.

Town hall 4: Atmospheric and Oceanic Teleconnection Across the Indo-Pacific Ocean (Indo-Pacific Teleconnection)
The variability of the Pacific and Indian Oceans is of great importance to the global and regional climate variations and predictability. Latest studies suggest that Indian Ocean plays an important role in ENSO variability and predictability. The dynamics are either teleconnected by the atmospheric bridge or through the oceanic channel of the Indonesian seas. In this session, studies about the interactions of Pacific and Indian Ocean climate variabilities through the atmospheric bridge and the oceanic channel are reviewed and compared, the effects of which on the predictability of ENSO and monsoon are discussed.

Town hall 5: WCRP Future
The mission of the World Climate Research Programme is to facilitate analysis and prediction of Earth system variability and change for use in an increasing range of practical applications of direct relevance, benefit and value to society. The Joint Scientific Committee is charged with providing guidance and oversight on future directions for WCRP and its activities. Several Core projects including CLIVAR contribute to the development and success of WCRP.
In this Town Hall, the JSC invites OSC participants to discuss their views on the future strategy of WCRP. A few presentations will be made by members of the JSC as well as by Prof Hui-Jun Wang, Chair of the China National Committee for the WCRP. A discussion will take place to address several questions such as: (1) What should be the novel areas and new directions in fundamental climate research? (2) What new observations do we need? – where and how else should we look? and (3) How can our communities best support science innovation?
We hope that the informal discussion will suggest novel and under-explored research directions, along with the tools and infrastructure needed to drive them. Such research will serve to enable societal preparedness for surprises emanating from within the climate system. While investigating these themes, we invite discussions on how WCRP structures and programmes can be best set up and prepared to identify and meet future challenges in climate research.

Town hall 6: Ocean Pathways of Glacier Melt: drivers, processes, impacts (Glacier Melt)
The Town Hall session "Ocean Pathways of Glacier Melt: drivers, processes, impacts" highlights the role of ocean circulation modulating glacier response (impact) to (on) the changing climate. The two main objectives are (1) to synthesize and share knowledge about different processes contributing to ocean-induced melting of glaciers in Greenland and Antarctica (warm water pathways to the marine-terminating glaciers and ice tongues, thermodynamics of glacier melt, circulation in the glacial fjords, ice melange and ice bergs dynamics) and (2) their expected regional and global impacts on fresh water budgets, marine ecosystem, and sea level.
This session engages several scientific disciplines: glaciology, ocean and climate dynamics, biogeochemistry, and marine biology. It offers a possibility to explore interdisciplinary and focused collaboration in terms of regional and global modeling, sustained observations, reanalysis systems, and operational services, model validation and improvement, interdisciplinary process observing programs, assessment of impact on coastal communities and the large scale climate. The scope of this session is bi-polar, with a goal to engage scientists active in the Northern (Greenland) and Southern (Antarctica) regions.
The Town Hall addresses the WCRP Grand Challenge on "Melting Ice & Global Consequences". It is relevant to International CLIVAR Panels on Ocean Model Development, Global Synthesis of Observations, and Climate Dynamics as well as to all the CLIVAR Regional Panels and in particular to the CLIVAR/CliC/SCAR Southern Ocean Region Panel (SORP) and to the US CLIVAR GRISO (Greenland Ice Ocean Science Network). It complements another activity held at the CLIVAR OSC Conference, the Poster Cluster "Ocean and cryosphere interactions in a warming climate".
The Town Hall aims to advance ocean-cryosphere interactions as one of the main themes of the new CLIVAR science plan, and possibly of a new dedicated CLIVAR/CliC Research Focus.

Town hall 7: Coordinated analysis of HighResMIP (HighResMIP)
The High Resolution Model Intercomparison Project (HighResMIP) (Haarsma et al. 2016) consists of a coordinated set of experiments to assess both a standard and an enhanced horizontal resolution simulation in the atmosphere and ocean. The set of HighResMIP experiments is divided into three tiers consisting of atmosphere-only and coupled runs and spanning the period 1950-2050, with the possibility to extend to 2100, together with some additional targeted experiments.
Presently 19 modeling centers have promised to participate in Tier 1 and at least 6 centers participating in the European H2020 project PRIMAVERA will participate in all 3 Tiers. This provides an unique data set for coordinated analysis.
The main purpose of the Town Hall meeting is to identify a topic of coordinated analysis of HighResMIP data that will result in a joint paper in a high impact journal. Obvious topics are small scale extreme events, such as tropical cyclones, for which the added value of HighResMIP is most prominent. Regional phenomena like monsoons, or a more general assessment of the benefits of increased resolution are also possible topics.
After defining the topic, the coordinated analysis and organization of it will be discussed. Due to the large amount of data, new approaches of coordinated analysis have to be devised. Instead of "bring the data to your script" the approach of a "bring your script to the data" appears to be more suitable for large data sets. This approach has been followed by the PRIMAVERA partners where the storage and post processing of the data will be on the JASMIN server at the UK. Whether a similar solution as for PRIMAVERA could be applied for HighResMIP will be discussed. Also the type of analysis and the need for additional experiments will be discussed.
Finally a working group and next steps that will lead to coordinated analysis and a joint publication will be formulated.
The anticipated outcome of this Town Hall meeting is: Initiation of a coordinated analysis of HighResMIP data for a specific topic that would result in a joint high impact paper. Defining a working group that will take the lead in this and that will organize next steps.
The coordinated analysis of HighResMIP simulations, focusing on a specific scientific and socio-economic relevant topic is a clear contribution to CLIVAR’s mission: to understand the dynamics, the interaction, and the predictability of the coupled ocean-atmosphere system. This for enabling better understanding of climate variability and dynamics, predictability, and change, to the benefit of society and the environment in which we live.

1-2 speakers outlining the purpose of this meeting and suggestions for coordinated topics and analysis (15 minutes)
Defining topic (15 minutes)
Organization of coordinated analysis (15 minutes)
Defining working group and next steps (15 minutes)

Town hall 8: CLIVAR Science Plan
The CLIVAR 2016 OSC has brought together over 600 people, including scientists with diverse interests from more than 40 countries and over 150 early career scientists. The CLIVAR leadership (Scientific Steering Committee) invites all participants to join in a review of the current draft of a new CLIVAR Science Plan and to discuss what is needed in the future to help advance the science being presented at the OSC. What should be the new directions of climate research, and what should be the respective CLIVAR goals as part of WCRP? Detlef Stammer, CLIVAR SSG co-chair, will summarize the current status of the new Science Plan that will be made available to participants in draft form prior to the conference. Contributions will be made at the town hall by representatives of WCRP and sister programmes on how CLIVAR fits with their future plans. Participants will have an opportunity to present their own views on the future of CLIVAR science and what kind of project is needed.

Town hall 9: Scoping out an agenda for a global Knowledge-Action Network on sustainable oceans and solutions (Future Earth)
Oceans, including coastal and nearshore areas, provide services essential for life on earth and to the history, culture and livelihoods of people across the globe. However, oceans are also facing multiple challenges from climate change, overfishing, acidification, de-oxygenation and pollution.
Recently, an increasing concern about the health of the oceans has placed oceans prominently on several global science-policy agendas, e.g. by inclusion in the set of Sustainable Development Goals and among the upcoming IPCC special reports. Accordingly, research and information activities on ocean topics exist in abundance. Why do we wish to establish yet another ocean research network, and what do we hope to achieve with it that could not be covered by the existing structures?
The new global network intends to be an umbrella over the major existing international activities in order to coordinate research and advocacy efforts more effectively across disciplines, regions, and societal sectors. To that effect, Future Earth has recently launched an open and inclusive Knowledge-Action Network on the topic of ocean sustainability, with the objective to address societal challenges through solutions-oriented, transdisciplinary research. The network wants to build on strong fundamental research and innovative agendas of projects, organizations and communities worldwide, including WCRP, SCOR, GOOS and many others.
The network is currently scoping out its shape and agenda over the coming decade by consulting with global communities of researchers and societal actors with stakes in the generation and use of ocean knowledge. As part of this process, this townhall session solicits discussion of ideas from the CLIVAR community about the most pressing societal challenges, scientific questions and inter- and transdisciplinary opportunities to inform the framing of the agenda of this new ambitious ocean network.

Town hall 10: Ocean and Climate Modeling and CLIVAR (Ocean and Climate Modeling)
The mission of CLIVAR is to understand the dynamics, the interactions, and the predictability of the coupled ocean – atmosphere system. To accomplish this mission and its related objectives, CLIVAR enables science through the collection and analysis of observations and the development and applications of models of the coupled climate system. CLIVAR modeling capabilities to advance CLIVAR science activities cover efforts primarily on ocean system models that include both forward models and ocean reanalysis frameworks. The reanalysis work is undertaken by the Global Synthesis and Observations Panel (GSOP). The forward modeling efforts occur within the Ocean Model Development Panel (OMDP) which is the only global modeling panel within CLIVAR. One of OMDP’s major foci is the development of ocean models for research in climate and related fields. Another one is to promote interactions amongst the broader ocean modeling community and, in particular, within CLIVAR, noting that all other CLIVAR panels and cross-cutting Research Foci teams have vital modeling needs.
The proposed Townhall Session is intended to provide i) brief summaries of recent developments and efforts from the ocean and coupled climate modeling, reanalysis, and decadal prediction communities, and ii) a discussion venue for all CLIVAR panels and Research Foci teams to discuss their modeling needs. The topics for the latter may include the next generation of ocean and climate models. The Townhall is expected to have representatives from the two WCRP modeling panels, i.e., WGCM and WGSIP, as well as the WCRP Modeling Advisory Council (WMAC).

Town hall 11 – Sustained Ocean Observing: How WCRP-CLIVAR and GCOS-GOOS build strong partnerships for global and regional implementation
Sustained ocean observing is essential to document and understand decadal and longer climate variability. The recently articulated Framework for Ocean Observing has suggested to develop a concept of a set of Essential Ocean Variables (EOVs) wich can be used to guide priority setting and system implementation. In addition research programs such as WCRP-CLIVAR are expected to support the development and innovation of new observing elements as well as spearhead the regional implementation by enhancing the efficiency and overall information content of integrated ocean observing systems (OOS). Several best practice examples exist for the Atlantic (AtlantOS), the Southern Ocean (SOOS, OOI, SOCCOM), the Pacific (TPOS2020), the pan-Arctic (SAON) and the Indic (IndOOS). One of the main goals for an integrated, fit-for-purpose global OOS is to enhance the efficiency and capability of all observing networks by strengthening the international partnerships within each of the networks to cover the global ocean. This town hall invites participants to a discussion of observation requirements for in situ systems in the global oceans with a focus on societal drivers (which includes research) and EOVs within the context of existing national capabilities, impediments, gaps and opportunities.
