The questions below are originally written with the perspective of providing user guidance related to EURO-CORDEX results, however many questions are broad and applies in a more general sense. This could mean that they can also be used by users of CORDEX information from other regions in the world and also in general every climate projection data user. Please note that there is a comprehensive user guide document provided by EURO-CORDEX and can be found at https://www.euro-cordex.net/imperia/md/content/csc/cordex/guidance_for_euro-cordex_climate_projections_data_use__2021-02_1_.pdf
The main topics are based on different categories suggested by the climate modellers as "typical" categories for which questions often arise. As an additional input questions asked by attendees at the C3S webinar series (https://climate.copernicus.eu/c3s-webinars-regional-climate-projections-europe) held in early March 2021. Please have a look also at the User Forum C3S webinars on regional climate projections for Europe for relevant topics from that webinar.
The main topics has primarily been chosen based on experience by the regional climate modellers in dialogue with ECMWF. The main topics fall into eleven different categories as listed below. For each question (underlined) it is attempted to answer in two levels where the first level is a short more general answer (in italics), while the second layer goes slightly more into detail sometimes including references for further reading when appropriate. Depending on the question, sometimes the answer includes a short recommendation (in bold face) on what a user may need to consider when using EURO-CORDEX climate projection data and some specific links (in red), when the information can be already found elsewhere. Extensive literature references can be found below (also at the specific questions).
