On September 11 2020 we held the 69th DA seminar online. The seminar was a joint presentation given by Prof. Shunji Kotsuki from Chiba University and Dr. Keiichi Kondo from JMA-MRI.
They spoke about their work using particle filters in use of high dimensional dynamical systems. Kotsuki-san talked about his development of a local particle filter with use with the LETKF da ta assimilation scheme and implementation of the Gaussian mixture to improve the local particle filter. His results showed that the added implementation of the Gaussian mixture outperforms the s tandard local particle filter for sparsely observed regions.
We would like to thank both Prof. Kotsuki and Dr Kondo for talking about their recent work and look forward to discussing more with them in future.
