Adjoint-based Data Assimilation of an Epidemiology Model for the Covid-19 Pandemic in 2020

Creators

  • 1. Universität Bayreuth

Description

Data assimilation is used to optimally fit a classical epidemiology  model to the Johns Hopkins data of the Covid-19 pandemic. The optimisation is based on the confirmed cases and confirmed deaths. This is the only data available with reasonable accuracy. Infection and recovery rates can be infered from the model as well as the model parameters.  The parameters can be linked with government actions or events like the end of the holiday season. Based on this numbers predictions for the future can be made and control targets specified.

With other words:

       We look for a solution to a given model which fits the given
      data in an optimal sense. Having that  solution, we have all
      parameters.
