nextGEMS‘ 5th Hazard Hackathon gathers over 80 participants in Wageningen for an exciting challenge

As part of the nextGEMS production stage for our high-resolution Earth system simulations, a new hackathon edition has been launched. The fifth nextGEMS hackathon is currently taking place in the central Netherlands, in the city of Wageningen, renowned for its university and vibrant student life.

From October 14th to 18th, 2024, more than 80 scientists, researchers, students, and other representatives from across Europe, North America and East Asia gather for the „Hazard Hackathon“ at Wageningen University. Here, they can collaborate, network, and tackle pressing challenges related to fire weather, precipitation, urban heat extremes, and more.

On the first day, Chiel Van Heerwaarden, a researcher and co-organizer from Wageningen University, kicked off the event with a welcoming speech and general information for the week to come. Following, scientists Dyvia Praturi from the Max Planck Institute for Meteorology and Xabier Pedruzo from the European Centre for Medium-Range Weather Forecasts (ECMWF) provided updates on the available ICON and IFS Earth system models‘ simulations.

Praturi encouraged participants to seek guidance and answers to their questions about the Easy Gems platform, while Pedruzo highlighted a recently published research paper detailing the advancements in IFS simulations.

During the opening session, Jasper Denissen from ECMWF introduced the audience to the Catchment-based Macro-scale Floodplain (Ca-Ma-Flood) model. He explained how its hydrological forecasts are being used in nextGEMS simulations and mentioned some of the Ca-Ma-Flood output variables that participants can work with, such as river discharge and flooded fractions.

Before the first day concluded with an exciting ice-breaker session that included some delicious local finger food and a round of pool and table tennis, Edgar Dolores-Testillos from the University of Bern presented the innovative structure of this hackathon. Unlike in the previous events, this time participants will have the opportunity to choose from five defined challenges: efficient data handling, fire weather, precipitation and temperature extremes and urban heat, energy production, and a „wild card“ challenge encompassing topics like tropical cyclones and extreme precipitation. Nevertheless, he emphasized that participants are also free to pursue their own or collective interests during the upcoming days of the hacking marathon.
