EnergAIze: dynamically downscaled extreme events using the regional climate model COSMO-CLM

As part of EnergAIze, eight selected extreme weather events (four extreme precipitation and four extreme wind) over Austria were simulated using two regional climate models: WRF and COSMO-CLM. Each event was initialized with the reanalysis dataset ERA5, a lead time of 10 days and simulated in high resolution (1.66 km for WRF and 2 km for COSMO-CLM) in order to analyse the performance under extreme conditions. For the dynamically downscaled extreme events, the Regional Climate Model COSMO-CLM was used over Austria with a 2km spatial resolution. Here, the COSMO-CLM dataset for one representative event (2021/01/13-2021/01/15) is published as NetCDF format. The data is available on an hourly basis and comprises several meteorological parameters (Total Precipitation, 10m Wind Speed, Surface Downward Solar Radiation, Surface Pressure, Cloud Fraction, 2m Temperature). The datasets for the remaining events are available upon request. Additional simulations for the same event using the Regional Climate Model WRF are published here: https://doi.org/10.5281/zenodo.15853653作为EnergAIze项目的组成部分，研究团队针对奥地利境内筛选出的8次极端天气事件（4次极端降水事件与4次极端大风事件），采用两种区域气候模式WRF与COSMO-CLM开展了数值模拟。所有事件均以再分析数据集ERA5作为初始场，起报提前量为10天，并采用高分辨率设置（WRF模式分辨率为1.66 km，COSMO-CLM模式分辨率为2 km），以评估两类模式在极端天气条件下的模拟性能。 针对动力降尺度得到的极端天气事件，本次研究采用空间分辨率为2 km的区域气候模式COSMO-CLM对奥地利区域进行模拟。 本次公开了其中一次典型事件（2021年1月13日至2021年1月15日）对应的COSMO-CLM模式模拟数据集，数据格式为NetCDF。该数据集为逐小时分辨率，包含多项气象参数：总降水量（Total Precipitation）、10米风速（10m Wind Speed）、地表向下短波辐射（Surface Downward Solar Radiation）、地表气压（Surface Pressure）、云量分数（Cloud Fraction）以及2米气温（2m Temperature）。其余事件对应的数据集需通过申请获取。针对该事件的WRF模式额外模拟结果已公开，链接为：https://doi.org/10.5281/zenodo.15853653
