Report CORDEX Science Advisory Team meeting, 9-12 September 2024, Santander, Spain

The Coordinated Regional Climate Downscaling Experiment (CORDEX) Science Advisory Team (SAT) met at the University of Cantabria in Santander, Spain, during 9-12 September 2024. Six SAT members attended in person and four joined online. In addition to the SAT members, representatives from the International Project Office for CORDEX (IPOC) and a representative from the World Climate Research Programme (WCRP) Secretariat were also present during the whole meeting. A day and a half of the meeting was open to the broader CORDEX community, to which CORDEX Points of Contact were invited, some present in person and many others attended online. Representatives for other WCRP activities were also invited to attend online for the open part of the meeting to discuss possibilities for future collaborations.

It was deemed important to have an extended CORDEX SAT meeting at this point in time in order to move forward in the restructuring of CORDEX, including selecting new SAT members and defining responsibilities. The open part of the meeting aimed to involve the CORDEX community in the discussions on the newly established Task Forces, new scientific topics, challenges, collaborations with various WCRP activities as well as with non WCRP initiatives and future plans.

The key outcomes from the meeting were 1. the agreement to increase the numbers of SAT members to reinforce transparency and diversity and thus to better meet the needs of the community as well as increase the collaboration with other activities. Additionally, given the relevance of the regional representativeness, the SAT agreed that all CORDEX domains should be represented by a SAT member and also SAT members need to cover the variety of expertises on the various topics tackled within CORDEX; 2. Establish and approve the Task forces to address the main emerging issues; 3. Identify future challenges for CORDEX and related to climate information on regional and local scales.
