From 16 to 20 September 2024 Sarah Ivušić, Patrik Jureša and Lidija Srnec participated in the HCLIM (Harmonie-Climate) working week held at KNMI in De Bilt, the Netherlands. During the event, we had the opportunity to meet our colleagues from HCLIM consortium in person and learned a great deal from them throughout the week. This experience was highly beneficial, as we will be running and interpreting the HCLIM numerical climate model for Croatia as part of our C3PO project.
