The week will feature the "Second International Conference on Subseasonal to Seasonal Prediction (S2S)", the "Second International Conference on Seasonal to Decadal Prediction (S2D)" as well as a joint segment addressing coming issues.

Aims and objectives:

i) to bring together the scientists, producers, and users who are at the forefront of S2S and S2D prediction and related research, development, and application areas to foster the exchange of information and knowledge between the communities towards more seamless subseasonal to decadal predictions;
ii) to highlight the current level of progress and accomplishments in S2S and S2D predictions;
iii) to identify the challenges for transitioning S2S and S2D prediction research efforts into operations;
iv) to review current abilities to make skillful predictions on timescales of interest;
v) to identify new initiatives, collaborations, and emerging science questions

Weather and climate variations on subseasonal to decadal timescales can have enormous social, economic, and environmental impacts, making skillful predictions on these timescales a valuable tool for policymakers. As such, there is a growing interest in the scientific, operational, and applications communities in developing forecasts to improve our foreknowledge of events. On S2S timescales, these include high-impact meteorological events such as tropical cyclones, floods, droughts, and heat and cold waves. On S2D timescales, while the focus broadly remains on similar events, e.g., precipitation, surface temperatures, and upper ocean heat content and their effects on the probability of these types of meteorological events, deciphering the roles of internal and externally-forced variability in forecasts also becomes important. The S2S and S2D communities share very similar, if not identical, scientific and technical challenges. These common challenges include forecast initialization and ensemble generation; initialization shock and drift; understanding the onset of model systematic errors; bias correction, calibration, and skill assessment; model resolution; atmosphere-ocean coupling; and linking research, operations, and users.

This meeting is open to all scientists, producers, and users involved in subseasonal to decadal climate predictions and related topics, including graduate students and early career scientists.

The 2018 EUMETSAT Meteorological Satellite Conference will be joined in the organisation and hosting of the event by the Estonian Environment Agency, the national provider for weather and climate services in Estonia.

The conference date is very fitting as it coincides with the celebration of the Centenary of the Republic of Estonia.

EUMETSAT has organised a meteorological satellite conference every year for over thirty years. During that time, the conference has become a key annual event for the meteorological and scientific communities where participants from around the world can meet to share their experience and knowledge during plenary, poster and workshop sessions.

The 2018 conference will discuss such topics as preparing for MTG and EPS-SG, atmospheric chemistry monitoring and applications, and climate and ocean monitoring. The conference location also lends itself to discussions on the topics of observations for the Baltic Basin, as well as Arctic monitoring and applications.

Further conference topics will incorporate developments in current and future meteorological satellite programmes, data access and nowcasting and high-resolution NWP.

Abstract submission: 1 December 2017 – 31 January 2018.

The 2018 Polar CORDEX Meeting is organized with the financial support from the funds of the Leading National Research Centre (KNOW) received by the Centre for Polar Studies for the period 2014–18, the World Climate Research Programme, and the Climate and Cryosphere (CliC) Project.

Overall workshop objectives:

The primary goal of the meeting is to review the status of on-going Polar CORDEX activities and to plan and coordinate future activities. First results of the pre-MOSAiC intercomparison based on ACSE2014 observations and next steps will be discussed. This will be a joint Arctic- and Antarctic-Polar CORDEX meeting, enabling participants from both communities to benefit by interacting closely. There will be plenty of time for discussions. All research groups that have started or are planning to contribute to Polar CORDEX activities, either by performing simulations or analysing Polar CORDEX data, are welcome to give presentations on their activities.

Preliminary Agenda:
Some initial ideas for sessions are for the following topics:

• Model evaluation
• Coupled modelling
• Process based studies
• Projections
• Impact studies
• Future activities/plans
• Stakeholder/user engagement

The Arctic is changing rapidly and is increasingly high on the international agenda. It is our joint responsibility to protect the fragile Arctic environment for future generations whilst promoting the sustainable development of the region.

In response to these developments, the European Union has developed an integrated policy on the Arctic. Engagement with Arctic stakeholders is one of the cornerstones of the EU's Arctic policy, adopted in April 2016 by the European Commission and the High Representative for Foreign Affairs and Security Policy.

It is for this reason that the European Commission will be organising the 1st Arctic Stakeholder Conference “Knowing, developing and connecting the Arctic” in Brussels on 17 September 2018.

The conference will be opened by Commissioner Karmenu Vella, responsible for the EU's Arctic policy, and will bring together around 200 Arctic stakeholders including representatives from local, regional and national authorities from the European Arctic and beyond, Arctic indigenous peoples and the EU institutions.

The purpose of the conference is to follow-up on the recommendations formulated in the final report of the Arctic Stakeholder Forum which identified investment needs and priorities for the sustainable development of the Arctic region. Discussions will therefore be organised around the following themes: Arctic connectivity, leveraging investment in the Arctic, and financial support for cross-border cooperation and Arctic science.

Moreover, the 2018 edition of the annual Arctic indigenous peoples Dialogue will also take place on the occasion of the conference. In order to enhance synergies and generate discussion, the Dialogue will be organised as a conference session open to all.

The conference will bring together around 200 Arctic stakeholders including representatives from local, regional and national authorities from the European Arctic and beyond, Arctic indigenous peoples and the EU institutions. Discussions will be organised around the following themes: Arctic connectivity, leveraging investment in the Arctic, financial support for Arctic regional cooperation and science.

The emphasis will be on EU funding and international cooperation but we are sure that the Conference would be relevant for scientists from an Arctic-network and community-building perspective.

The 25th annual West Antarctic Ice Sheet Workshop will be held this September at Stony Point Center in Stony Point, NY, followed seamlessly by the Thwaites Glacier Program meeting. The WAIS Workshop begins Sunday late afternoon, September 16 and ends with a 1-1/2 day section on Thwaites and Pine Island Glacier and the planned Thwaites Glacier
Program. On Wednesday afternoon, the discussion will turn to the Thwaites Program preliminary research and coordination, concluding Thursday with discussion on logistics for the future proposed field seasons. (The Thwaites awards have not yet been announced.) Please consider the relevance of these later sections to your own work when planning your stay.

Registration fees have not yet been determined, and we welcome people to attend both meetings or the one of most interest. More information will be shared in the coming months through this list.

We would like to invite you to the ISMIP6 workshop "Developing process-based projections of the ice sheets’ contribution to future sea level" to evaluate the output of the CMIP6 climate models and obtain forcing for standalone ice sheet model experiments. This workshop will be key for establishing the experimental protocols for the ice sheet model simulations that target the IPCC AR6 report.

Scientific program:

The program will start Tuesday morning at 9:00 and end Thursday noon at 12:30. Most participants (from outside the Netherlands) will arrive Monday evening.

Registration is now closed.

The Sea Ice Prediction Network–Phase 2 (SIPN2) will convene an open webinar titled An Overview of MOSAiC: The Multidisciplinary drifting Observatory for the Study of Arctic Climate. This webinar will provide an overview of the interdisciplinary international MOSAiC program and ongoing work on the causes and consequences of an evolving and diminished Arctic sea ice cover.

Webinar Program:

MOSAiC is a large interdisciplinary international program addressing an overarching question of "What are the causes and consequences of an evolving and diminished Arctic sea ice cover?" The centerpiece of MOSAiC is a year-long drift experiment from September 2019 to September 2020. In MOSAiC, models are being used to inform observations and observations will be used to enhance models. MOSAiC is taking an interdisciplinary approach with elements investigating the atmosphere, ice, ocean, ecosystem, and biogeochemistry. Observations will be conducted on three primary scales; the central observatory (5 km), the distributed network (50 km), and the large scale (1000s km). This presentation will give an overview of MOSAiC, with special attention on the sea ice program.

Webinar Speaker:

Don Perovich is a Professor at the Thayer School of Engineering, Dartmouth College. His research is focused on the geophysics of sea ice, with particular emphasis on electromagnetic, thermodynamic, and morphological properties. A central element of his work is observing and understanding the role of the sea ice albedo feedback in the Arctic climate system.

More details, including registration instructions, will be announced closer to the event. The webinar will be archived and available online after the event.
