WCRP Programme/Project offices meeting on 29 June

The WCRP International Project Offices (IPOs) and Joint Planning Staff (JPS) meet online regularly and the latest meeting was held on 29 June 2020, hosted by the CORDEX office.

Key activities and status were reported from all the IPOs during the telecon and the JPS reported on plans for the coming Joint Scientific Committee (JSC) meetings.

Iréne Lake, the CORDEX IPO director, presented some of the ongoing CORDEX activities:

  • CORDEX Experiment Design for dynamical and statistical downscaling of CMIP6.
  • CORDEX White Paper on the Future Regional Scientific Challenges for CORDEX.
  • CORDEX workshops on Capacity Development, Flagship Pilot Study meetings and other regional workshops planned for 2020 will either be held online in the fall or postponed until 2021.
  • Three longer online CORDEX Science Advisory Team-meetings were held 25 June, 30 June and 2 July to outline the way ahead.
  • There will shortly be a call for Flagship Pilot Studies announced.


Messages from the telecon included:

  • IPO staffs are gradually returning back to offices depending on the local situation.
  • All WCRP projects/programmes are outlining their roles in the new structure of the WCRP.
  • An extraordinary JSC session will be organised online in Nov/Dec of 2020
  • The JSC-42 will be organised in May/June 2021. Modality and venue are yet to be decided.
  • The WCRP calendar is being finalised with input from all IPOs.
  • Many activities are being postponed to 2021 due to Covid-19 and the possibility to have joint or back-to-back events was raised.
  • The next JPS and IPOs telecon will be organised in September and be chaired by GEWEX office.

CORDEX Climate Information at EGU’s Geoscience Meeting

Modelling the future climate on a regional scale requires both cooperation and computer power. Part of the work of CORDEX is to support countries that do not have the resources to produce regional climate information and to enable them to take advantage of global cooperation. At the big EGU Geoscience meeting, EGU2020, which took place on 4-8 May 2020, information produced within the CORDEX community was presented at several of the sessions.

The CORDEX (COordinated Regional Downscaling EXperiment) project office is located at SMHI in Sweden, and coordinates global cooperation for the development of climate scenarios and models on local and regional scales. CORDEX work is very important for the IPCC reports, including the forthcoming Assessment Report 6 (AR6).

Several of the sessions at EGU2020 discussed regional climate modelling from different aspects and therefore had strong links to CORDEX work.

Prioritising particularly vulnerable areas

CORDEX is about working towards sustainable societies by helping decision-makers and others to understand the risks associated with a changing climate. Studies based on CORDEX information show the importance of working with high resolution and with well-described physical processes.

– In this way we can respond to specific regional problems, for example by predicting precipitation more accurately in regions with complex topography. At the same time we can see changes in land use and regional climate and consequently improve our knowledge about planning and risk management in areas with low capacity, says Iréne Lake, Director of the International Project Office for CORDEX at SMHI.

Many of the analyses and experiments presented at the conference were based on CORDEX CORE results which are simulations carried out under specified minimum requirements, for example for resolution (grid spacing) and the time span. Since regional climate modelling requires huge amounts of computer power, the CORDEX network has suggested a priority list, including areas which are particularly vulnerable to changes in the climate.

The climate at the poles significantly affects the rest of the world, both socio-economically and ecologically. Regional climate models also play an important role here, to increase our understanding of the mechanisms affecting life environments, both historically and in the future.

Strengthening cooperation between experts and researchers

One of the goals of EGU is to create and strengthen the cooperation between experts and researchers from various disciplines. Representatives from both CORDEX and SMHI have been important contributors to several of the sessions. For example one of the CORDEX pilot projects on convective processes over Europe and the Mediterranean was highlighted during a session on atmospheric modelling, where the resolution needs to be high enough to describe the convection correctly.

CORDEX was also included in an Open Science session with the purpose of developing innovative tools and techniques to integrate, manage, evaluate and spread information for different systems for ESSP (Earth Systems Science Prediction).

Working for a sustainable future

– The challenges that we all experience and will face due to climate change permeate all parts of research and the community. EGU is an established and important forum for sharing experience and following the latest developments. SMHI and CORDEX are bringing new insights that can help us to be even better at contributing to a sustainable future for everyone living on our planet, says Iréne Lake.

The 3rd Baltic Earth Conference was successfully held online 2-3 June

At the 3rd Baltic Earth conference online last week new results from coupled regional climate models were presented, for instance on ‘Moving climate zones and climate change impact on anomalous weather phenomena in the Euro-Cordex / Baltic Sea region’.

New high-resolution (25km) CORDEX CORE simulations available

The regional climate simulations of the CORDEX CORE activity are now available at the ESGF, look for the XXX-22 domains.

For other RegCM simulations not available at the ESGF, please find further information on data access here

The simulations cover all major inhabited areas of the world at a resolution of 25km. Two RCMs (RegCM from ICTP and REMO from GERICS) are used to downscale three GCMs for two RCPs (RCP2.6 and RCP8.5).
