To be considered for travel support, please register by August 1st, 2019.

Ruth Mottram will host the event.

Travel Information:

The meeting will be hosted at DMI, on the outskirts of Copenhagen but easily accessible by bus or s-train to neighbouring  Ryparken station. Or do as the Copenhageners do and borrow a bicycle! Travel around the city by public transport is easy to organize using the website and app Rejseplanen.dk .

Copenhagen is served by a major airport with fast metro and rail connection to the city centre and also has rail links to Germany and Sweden. To accommodate those trying to reduce their travel CO2 footprint, the meeting will start late on Monday and finish early on Wednesday to enable those on the sleeper train to Hamburg to make their connections.

There are a very full range of hotels, BnBs and hostels in Copenhagen but rates can be quite high, it is worth booking well in advance! Many of our visitors use the centrally located  cabinn hotels.

Further information on visiting the city can be found via VisitCopenhagen.

This meeting is organized with the financial support of the Government of Canada through the federal Department of the Environment, the World Climate Research Programme, and the Cllimate 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. This will be the first time that a joint Arctic- and Antarctic-Polar CORDEX meeting will be held, 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
Impact studies
Future activities/plans
Stakeholder/user engagement

Accommodation and travel information

Cambridge is served by three major airports: London Stanstead, London Heathrow, and London Gatwick (the furthest away). Information on how to travel to the Cambridge from these airports is available at https://www.bas.ac.uk/about/contact-bas/travel-to-bas-cambridge/.

Accommodation in Cambridge can be found through the official visitor information website at http://www.visitcambridge.org/accommodation. BAS is located on the outskirts of Cambridge, but visitors would probably enjoy staying in a more central location of Cambridge.

A number of visitors to BAS have previously stayed at the Lensfield Hotel, which is centrally located, and close to the Cambridge train station (http://www.lensfieldhotel.co.uk/).

BAS is around a 30-40 walk from the city centre. Details on how to reach BAS from the city centre and the railway station are given at https://www.bas.ac.uk/about/contact-bas/travel-to-bas-cambridge/.

Further visitor information can be found at http://www.visitcambridge.org/visitor-information.

2016 Arctic CORDEX Meeting

From 28-30 November 2016, Arctic CORDEX will have a meeting hosted by Uni Research and the Bjerknes Centre for Climate Research in Bergen, Norway.

Overall Workshop Objectives

The objective of this annual workshop is to present and discuss results from individual Arctic Cordex models, but also from the multi-model intercomparisons. Also, we will discuss the next steps of further joint analyses and individual simulations. The coupled modeling aspect is one particular highlight. Another topic linked to both scientific aims and user-communities are higher-resolution simulations. We aim for a better linkage to the WCRP Grand Challenges on Climate Extremes and Regional Climate Information. Associated with this we want to include stakeholder/user engagement in the discussion.

Preliminary Agenda

Monday, Nov 28, 1-6pm

Welcome and introduction (Muralidhar Adakudlu)

Session 6 Future activities/plans

Here, we aim to discuss our next activities, ideas of analysis, meetings, etc.

Please prepare for these possible questions:
What are ideas of further model intercomparisons or model-observation comparisons or synthesis? Participation in satellite-based multi-model evaluation proposal (Duane Waliser’s mail)? Are there phenomena or processes of common interest?  Is anyone interested in runs with higher horizontal resolution? Is there any common interest for one specific smaller region? What about IPCC-AR6 (plans, simulations, domain, schedule)? Opinion about Cordex CORE (Irene Lake’s mail)? Is there any interest to think about an Arctic Cordex FPS? What about links to other related activities (e.g. SIMIP, FAMOS, MOSAiC, stakeholder-related, etc.)? ……

Additional information:  

Bergen is generally dark and wet during November. It could be little cold as well. But one could get lucky as well. You never know!

Regarding the transport from the airport, you have the airport bus that gets you to the city center. Just FYI, there are two routes from the airport to the city. Both take almost the same time (about 35 minutes). The bus stop is right at the exit of the arrival gate at the airport. The stop to get down varies depending on your hotel. For 1 & 2, it will be ‘bystasjon’. For 3, 4 and 5, it is ‘festplassen’ (You need to walk for 10 minutes to get to #3). For 6, it is ‘bryggen’ which is also the last stop. The ticket costs about 110 NOK. If the bus timing doesn’t suite you, there are taxis available. It would cost around 500-600 NOK depending on the day and the time of arrival.

2015 Arctic CORDEX Meeting

1-AWI-Potsdam-(© AWI)From 26-28 October 2015, Arctic CORDEX will have a meeting at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, in Potsdam, Germany.

AWI-Potsdam; building A43; see http://www.awi.de/en/about-us/sites/potsdam.html

Contact Annette Rinke or John Cassano for more information.

Overall Workshop Objectives

The objective of the workshop is to present and discuss first results from individual models, but also from multi-model intercomparison studies. Further joint analysis will be discussed with the aim to establish linkages and contribute to the WCRP Grand Challenges on Climate Extremes and Regional Climate Information.

More simulations to downscale CMIP5 GCMs future projections for the Arctic CORDEX domain are planned. Focus will be on RCM simulations for the RCP8.5 scenario. We will discuss and plan these simulations with the goal of having a good RCM-GCM matrix, i.e. the groups will try to run their RCM with at least two different GCM forcings.

We will also seek ways to strengthen our link to the Arctic Council “Adaptation Actions in a Changing Arctic” (AACA) project. The AACA project looks at future climate impacts, their interactions with other non-climate and socio-economic drivers of change, and the relevance of this for designing adaptation policies. We want discuss which Arctic CORDEX results and analysis are relevant for and should feed into the upcoming AACA report.

Preliminary Agenda

26 Oct (Monday) start 13:00

1. Discussion session on downscaling ERA-Interim (validation runs)
Each modeling group should give a short (ca. 15 minute) presentation on the status of their ERA-Interim-driven Arctic CORDEX simulations
(no representative from Ulg-MAR, CCCma-CanRCM4)

2. Discussion session regarding multi-model intercomparisons

To register

If you cannot see the form below, please contact the CliC office to register.

Accommodation and Local Information

Potsdam is situated in northeastern Germany, just southwest of Berlin. Motorways, airports and major railway lines allow easy access from within and outside of Germany. The address for AWI is Telegrafenberg A43, D-14473.  The information below is taken from AWI's website, more details and a map can be found on their website.

By plane

The closest major city to Potsdam is Berlin, which has two airports: Tegel (TXL) and Schönefeld (SXF). From any of these airports, Potsdam can be reached by public transport (see below).

Tegel (TXL) airport
From Tegel (TXL) airport take bus line X9 or 109 to station ‘Zoologischer Garten’ in Berlin, follow the signs to the regional train station, then take the regional train RE1 to Potsdam main station (‘Potsdam Hauptbahnhof’).

Schönefeld (SFX) airport
From Schönefeld (SFX) airport take the regional train RB 22 to ‘Potsdam Hauptbahnhof’. Alternatively, take the suburban train (S-Bahn) line S9. Change trains at station ‘Westkreuz’, from where the S7 goes to "Wannsee". Change there a second time and take the S1 directly to ‘Potsdam Hauptbahnhof’.

By train

Most regional fast trains bypass Potsdam on their way to Berlin. Generally, we recommend getting off at station ‘Berlin Hauptbahnhof’ and taking the regional train RE1 to ‘Potsdam Hauptbahnhof’ (Potsdam main station), which takes approximately 20 minutes.

To get to Potsdam from Berlin main station, you need an ABC Ticket (3.20 Euro) which you have to get stamped on the platform.

How to get to the Research Unit in Potsdam
The Research Unit Potsdam of the Alfred Wegener Institute is located at Telegrafenberg, the historic science campus ‘Albert Einstein’, south of Potsdam city centre. From the railway station ‘Potsdam Hauptbahnhof’, a 20 minute walk takes you to the campus at Telegrafenberg. Alternatively, a taxi takes less than 5 minutes and costs approximately 5 Euro. Local public transport in Potsdam (bus and tram), does not service Telegrafenberg directly. There are two buildings of the Alfred Wegener Institute on campus. The old one (A43) is located on the right-hand side, about 50 m from the entrance to the campus, and the new laboratory building (A45) is located about 100 m left of the campus gateway.

By car

Potsdam is located just southwest of Berlin, within the ‘Berliner Ring’, a circular motorway surrounding Berlin. From nearly all directions, the simplest way to Potsdam is via the ‘Berliner Ring’ (A10), exit 17 ‘Potsdam-Süd/Michendorf’, subsequently following the road B2 to Potsdam. 600 metres past the ‘Potsdam’ city limit sign, turn right into ‘Brauhausberg’ street, also signposted for ‘Landtag’. After 1.2 km, turn right again into ‘Albert-Einstein’-street (signposted ‘GeoForschungsZentrum’), which will lead directly to the entrance of the campus.


2014 Polar CORDEX Meeting

The Polar CORDEX meeting was held on June 17, 2014, from 14:00 to 15:00 during the 3rd Lund Regional-scale Climate Modelling Workshop, 21st Century Challenges in Regional Climate Modelling, Lund, Sweden, 16 - 19 June 2014 (http://www.baltex-research.eu/RCM2014/)

For more information on the meeting, please contact Annette Rinke. For more information on Polar CORDEX visit: http://www.climate-cryosphere.org/activities/targeted/polar-cordex

The meeting notes are available for download here.

2013 Arctic CORDEX Meeting

The Arctic CORDEX Meeting was held on November 8, 2013 in Brussels, Belgium from 9am until noon. It was held after the general CORDEX meeting (http://cordex2013.wcrp-climate.org/venue.shtml). Download the meeting notes.

Arctic-CORDEX (Coordinated Regional Downscaling Experiment - Arctic Domain) (http://wcrp-cordex.ipsl.jussieu.fr/index.php/community/domain-arctic-cordex) is the Arctic portion of the international CORDEX initiative (http://wcrp-cordex.ipsl.jussieu.fr/). CORDEX is a WCRP-sponsored program to organize an international coordinated framework to produce an improved generation of regional climate change projections worldwide for input into impact and adaptation studies within the AR5 timeline and beyond. Currently, the core of Arctic-CORDEX consists of dynamical regional climate (RCM) simulations for hindcast (ERA-Interim and GCM-driven historical simulations) and scenario (GCM-driven rcp4.5, rcp8.5 simulations) periods. Currently Arctic-CORDEX data has been provided by CCCma, HIRHAM, RCA, and WRF regional climate models.

The primary goal of the workshop was to review the current status of on-going Arctic CORDEX activities and to plan and coordinate future activities.
All research groups that have started or are planning to contribute to the Arctic CORDEX activity, either by performing simulations or analyzing Arctic CORDEX data, were encouraged to give a short presentation on their activities.
These presentations discussed which simulations are finished, running, and planned and what analyses are completed or planned.
After these overview presentations the remainder of the meeting was dedicated to an open discussion of future activities and methods for coordinating these activities.

Workshop organizers John Cassano ( ) and Annette Rinke ( ).
