  • Observations & Modeling

    Diagnoses Quantitative precipitation estimation (QPE) Climate change monitoring* Assimilation in numerical weather prediction

    (NWP) models* Verification

    Confidence and credibility in QPF is achieved throughverified

    * Observing System Simulation Experiments(OSSE)

    * NWP can improve QPE through assimilation

    * Indicates a direct linkage between the observational and modeling components of this vision
