CORDEX is involved in the organisation of the Asia Climate Risk and Impact Strategic Workshop that will be part of the 5th international Vietnam Conference on Earth and Environmental Sciences 2025 held in November in Quy Nhon. Keep your eyes open for more information and check out the conference website: iVCEES2025

If so, your inputs would be greatly appreciated !

As part of the joint CLIVAR-OMDP and RIfS-CORDEX Task Force on Regional Ocean Climate Projections, we are assembling a record inventory of regional ocean model projection simulations as both a resource for the regional ocean modeling community, to inform recommendations regarding community needs and priorities.

We are collecting information for this inventory by way of voluntary survey with the intent of making synthesized information publicly available via the Task Force web page.

You’re invited to take the survey using the QR code below or using directly this link https://forms.office.com/e/18yxHGqWPZ :

Please submit your response by 1 July 2025.

The survey only takes less than 10 minutes to complete.

Please fill free to forward this survey to potentially interested colleagues and modeling programs.

In early 2025, a major data loss at DKRZ significantly impacted the availability of CORDEX-CMIP5 data through the ESGF, as many datasets—without existing replicas—were stored exclusively at that node. Despite the hard work to recover as many data sets as possible, the loss still affects approximately 20,000 datasets (over 200 TB), spanning multiple CORDEX domains, variables, and output frequencies. A full list of the missing datasets can be found here.
All CORDEX users are encouraged to check their local CORDEX-CMIP5 data archives (downloaded from ESGF) to help mitigate the impact of this data loss. A simple script is available in the esgf-data-loss/ directory to assist in identifying whether your system contains any of the missing data.

bash locate_available_data.sh /path/to/your/CORDEX/data/following/ESGF/directory/structure

If you discover that you hold any of the affected datasets, please open an issue in this repository or contact: datasupport@cordex.org.
Some of the most commonly used variables from the CORDEX-CMIP5 archive remain accessible via the Copernicus Climate Data Store (Diez-Sierra et al. 2024).

The CORDEX Task Force on CMIP7 has prepared a survey to collect information about plans from modelling groups:

Survey on potential commitments for CORDEX-CMIP7 in time for AR7

The CORDEX Task Force (TF) on Preparation of CORDEX-CMIP7 is preparing the way to downscale the upcoming CMIP cycle, starting with the CMIP7 Fast Track, which will respond to the needs of the IPCC 7th Assessment Report (AR7). In this respect, the TF would benefit from prior knowledge of existing national or institutional commitments to downscale the CMIP7 Fast Track in time for AR7 or other assessments/adaptation plans in the short term. This brief survey collects key information to assist the TF work.

Please find the survey here: https://forms.gle/ancgPtUaytwBkYS5A

The deadline for answering is extended until end of May.

CORDEX together with ESMO and RIfS are organising a Townhall with panel discussions and questions on Innovative Approaches to Observations and Modelling for Improved Climate Information and Services at EGU on Monday 28 April 19.00-20.00 CEST. Read more about the townhall here.

The same day there is also the session Regional Climate Modelling, including CORDEX at 14:00-17.55 CEST with both oral presentations and posters. You can find more information about this session here.

There are also CORDEX presentations in other sessions so check out the full EGU25 programme.
