AtmoRep

The short-term forecasting skills of the pre-trained AtmoRep model are being tested against the numerical prediction models from ECMWF (IFS) and DWD (ICON), as well as the main machine learning based forecasting algorithms now available, like FourCastNet. We are working to extend the AtmoRep forecasting skills to medium-range forecasting. We will also investigate the impact of additional variables related to the atmosphere-ocean interactions.

Downscaling, also known as super-resolution in computer vision, aims to increase the resolution of a coarse spatial input. For atmospheric fields, this can be achieved using weather forecasting models, which, however, is computationally expensive. With the pretrained transformer, one can use the decoder for downscaling to reach resolutions of a few kilometers. In particular, we will be using the COSMO REA6 Reanalysis dataset, which reaches a resolution of 6 km.

The presence of biases in models can cause shifts and trends in reanalyses that can lead to sub-optimal forecasts. In AtmoRep we will correct for biases in the total precipitations forecast by fine tuning the pre-trained model directly on radar observations. We will use the German RadarKlimatologie (RADKLIM) dataset, which consists of a radar-based, high-resolution precipitation dataset over Germany from 2001 to the present day.

Christian Lessig is assistant professor at Otto-von-Guericke-Universitat Magdeburg. His background is in computer science but he also works today in scientific computing and numerical analysis. In the last years, his research moved towards addressing climate change, in particular by developing hybrid weather and climate simulation models that combine classical discretizations of the governing partial differential equations with neural networks that account for phenomena that are too expensive to simulate or whose physics is not well understood.

Ilaria Luise is a Senior Research Fellow at CERN, the European Center for Nuclear Research in Geneva. She works as a physicists within the Innovation Division of the CERN IT-Department. Her background is in high energy physics and big data management. She is Co-PI of the EMP2 project at CERN, which is part of the CERN Innovation Programme on Environmental Applications (CIPEA). The EMP2 project aims at implementing the AtmoRep model into a digital twin engine. This is performed in collaboration with the EU funded InterTwin project and the Digital Twin initiative at CERN.
