  7. 5. Implementation of a Block Krylov Algorithm in Variational Data Assimilation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Clémentine Gas; [2019]
    Nyckelord :;

    Sammanfattning : Numerical weather prediction relies on two major components: sophisticated atmospheric forecast models and equally important data assimilation algorithms. Data assimilation (DA) is the process used to produce the best estimate of the state of a model, using an Earth system numerical model and observations. LÄS MER
