IMT-Atlantique & RIKEN Online Joint Seminar Series (Jointly with Data Assimilation Seminar Series)


  • Dates: Feb.17 - Apr.14, 2021
  • Language: English
  • Place: Zoom
 To join the video meeting, please contact the following address in advance.

Theme: Statistical Modeling and Machine Learning in Meteorology and Oceanography

This online joint seminar series follows the first and second joint RIKEN-IMT Atlantique workshops in 2019 and 2020. The main topic is the fusion of Data Assimilation (DA) with Artificial Intelligence (AI) in the fields of Meteorology, Oceanography, and Climate. The use of AI and statistical techniques such as neural networks in geophysics has a potential to enhance our knowledge and to improve physical models’ performance by exploiting more from available observations and by accelerating DA workflow for real time response. This seminar series aims to exchange ideas about potential future research on the fusion of DA and AI with HPC in the research fields of meteorology and oceanography for enhancing future collaborations between RIKEN and IMT-Atlantique based on the international agreement signed in 2019.
