Topic: Ocean Data Assimilation

Friday, February 10, 2023 from 15-17 UTC

Organisers and Conveners: Max Yaremchuk (NRL, US), Hao Zuo (ECMWF, UK), Nora Schenk (DWD, Germany)

Data assimilation is used more and more widely in operational oceanography and to produce climate reconstructions. With the advent of coupled NWP at many operational centres, improving methods for ocean (and coupled) data assimilation becomes even more important. We invite contributions on ocean DA and coupled ocean-atmosphere DA (with the focus on the ocean component) in all types of models.
