Parallel session D: CORDEX in Practice
All D-sessions in Trieste are held between 14.30-17.00 CEST
D1. CORDEX-Ocean: Towards a CORDEX framework for Ocean Regional Climate Modelling (online and Trieste)
Conveners: Samuel Somot (Med-CORDEX), Marine Herrman (CORDEX South-East Asia), Markus Meier (EURO-CORDEX, Baltic Earth) and Tereza Cavazos (Central America CORDEX).
Since its inception, the CORDEX initiative has focused mainly on continental areas, leaving oceanic areas aside. However, today, the regional climate scientific community is facing more and more questions from citizens and policy makers regarding the necessary adaptation of marine ecosystems and maritime or coastal activities to ongoing and future climate change. This D-session proposes to assess the challenges in regional ocean modeling at climate scale, to identify the obstacles to overcome in order to reach a large-scale international coordination, and to reflect on the opportunity to develop a CORDEX framework for Ocean Regional Climate Modelling.
Oral abstract submission.

D4. Climate services for transformation using CORDEX datasets: best practices using FAIR principles and innovative tools (online and Trieste)
Conveners: Claas Teichmann (GERICS), Lars Buntemeyer (GERICS), Helena Martins (SMHI), Angel Muñoz (BSC), Armelle Remedio (GERICS), Christine Nam (GERICS), Francisco Doblas-Reyes (BSC), Gaby S. Langendijk (GERICS), Katharina Bülow (GERICS), Ludwig Lierhammer (GERICS), Marjana Brkić (CPN), Marta Terrado (BSC), Peter Hoffmann (GERICS), Ross D. Dixon (UNL).
In this session, we want to present and discuss methods and best practices in current climate services as well as an outlook of how future developments can be designed under FAIR conditions. User experiences show an increasing demand for guidance on how to use CORDEX data in climate services which calls for discussions on community work inside and outside of CORDEX and how this can be improved. Furthermore, upcoming simulations for use in climate services should involve users from different backgrounds in a co-production design process to tackle their requirements and provide useful climate services products.
At the end of the session, we will have a demo part involving hands-on code examples to explore some current developments and tools for working with regional climate model data and its application in climate services.
Abstract submission.

D5. Coordinated Training Programs (online and Trieste)
Conveners: Chris Lennard, Fredolin Tangang and Maria Laura Bettolli.
Training and capacity building programs in regional climate downscaling and data analysis are vital to develop the next generation of climate researchers, especially in developing countries. Implementing them in a coordinated manner under the CORDEX and WCRP Academy umbrella would add to the effectiveness and impact of these programmes.
In relation to this there are a number of relevant questions that require addressing such as: What are the practicalities of running trainings in different parts of the world? Is there an ‘optimal/preferred’ number of participants and number of days for different kinds of workshops? What is the approximate cost in different regions? What works well for different formats – on site, online, hybrid? What have we learned from Covid? What tools are needed/recommended for dynamical/statistical downscaling and for viewing/analyzing data? Do the participants need some prescribed background and what competence/experience is needed from lecturers? Is it best to mix experts and users to bridge the gap between science and society? What training and capacity development themes need (still) to be addressed?
There have during the years been a number of such training workshops conducted in Asia, Africa and Central/South America. This D-session primarily provides a platform for exchanges of experiences and discussion about best practices to run capacity development activities within CORDEX. The outcomes could lead to a drafting of some guidelines/standards for anyone to use as a baseline when organizing a ‘CORDEX training/workshop’, and contribute to collaborations with the WCRP Academy.

D6. High resolution urban climate modeling and regional climate change – progress and challenges for CORDEX (online and Trieste)
Conveners: Dr. Tomas Halenka, Dr. Gaby S. Langendij, Dr. Sri Raghavan and Mr. Muhammad Ammar.
This session focuses on urban areas and its interactions with the regional climate, as well as on the challenges and opportunities to include an improved urban representation in regional climate models for future CORDEX simulations. It will highlight new developments and results within urban modelling initiatives, including the FPS URB-RCC. The session also invites papers and discussions on what has been achieved in terms of high/extra fine (sub-km) scale urban climate modelling, especially under climate change.

D7. Training on how to compare bias-corrected Regional Climate Models (RCMs) with Empirical Statistical Downscaling (ESD) for robust future climate change projections, exploring tools/products (online and Trieste)
Conveners: Huikyo Lee (Jet Propulsion Laboratory, California Institute of Technology, USA), Rasmus Benestad (Norwegian Meteorological Institute (NMI), Norway), Abdelkader Mezghani (NMI), Kajsa Parding (NMI), Ian Brosnan (NASA Ames Research Center, USA), Alexander
Goodman (Jet Propulsion Laboratory, California Institute of Technology, USA).
This session will aim at training the users on how to perform a comprehensive analysis comparing both bias-corrected regional climate model output and empirical-statistical downscaling results against observations to obtain a robust and reliable climate change prediction. It will follow up work carried out during the #ConCordOslo20221 workshop and previous CORDEX D sessions.
We will explore CORDEX RCM output and statistically downscaled products, such as NASA Earth
Exchange Global Daily (NEX-GDDP-CMIP6) and region-specific ESD-seasonal Downscaled Projections. We will be using tools such as the R-esd package developed by the Norwegian Meteorological institute and the Regional Climate Model Evaluation System (RCMES) developed by NASA. This includes hands-on training about extracting, processing, downscaling, bias-correcting, visualizing, analyzing and manipulating datasets. The training will also address two approaches in ESD: “downscaling weather” and “downscaling climate” and we will explain new concepts such as “common EOFs” as a framework for ESD predictors.
The expected outcome of this training workshop is 1) to disseminate statistically downscaled multi-model CMIP6 GCM ensembles and open-source software to analyze the downscaled dataset to the CORDEX community, 2) to train potential users of NEX-GDDP-CMIP6 to make use of cloud-based resources, and 3) to increase communication and collaboration between different CORDEX domains.
