Project Title

Using GEV and sMEV to analyze future extreme precipitation

Getting Started

The software was developed as part of the study "Benefits of the simplified MEV for analyzing hourly precipitation extremes in a changing climate" (https://doi.org/10.5194/egusphere-2025-6419). A major part of this software is based on software from Marra, F., & Peleg, N. (2025) and Francesco Marra (2024) and which uses several other papers in turn (more informations in the /Matlab_Functions folder).

Using this code makes it possible to reproduce results in the study, which are based on gridded climate model simulation. The original COSMO-CLM simulations can be found under the DWD ESGF data base (https://esgf-data.dwd.de/csys/project/dwd-cps/, Haller 2022). It also includes derived data of an example model domain, which can be reproduced using the provided software (more informations are provided in the corresponding README).

Prerequisites

The only prerequisites are a Matlab version R2023b or newer and a Python distribution to plot the 2D maps (more info in /Images). Note that the calculations can be very computationally expensive, mostly depending on the number of iterations used for the bootstrapping.
