25th Apr 2024 | - S3 object storage in HSM: prototype (Malte Thoma and Pavan Kumar Siligam )
- Q&A
- Presentation: AI/ML and climate analysis - it all starts with data - Christopher Kadow, DKRZ
- Christopher is the leader of the Data Analysis group at DKRZ. Among other tasks his group have developed the NextGEMS data portal, develop analysis tools, they are organizing Machine Learning workshops, working on the future DKRZ object storage, workflows with zarr data format...
- Abstract:
This talk gives an overview of the topics of the new department Data Analysis at DKRZ - using new technologies for climate research and data handling on the HPC Levante. We demonstrate the successful transition of an AI image processing method into a climate data reconstruction application. In addition to exciting results of reconstructed climate events in the distant past dating back to 1850, the importance of the data base in our field will be addressed. Understanding the content of the data collection is key to the proper application of the latest AI/ML and climate analysis. Linking different data sources for such target variables is part of the BMBF projects ClimXtreme, RegiKlim and WarmWorld - e.g. www.gems.dkrz.de . The results presented link observations with climate model simulations and, in combination with ML, provide an unprecedented insight into different climate applications such as data assimilation, downscaling and digital twins.
