Weakly Coupled Ocean–Atmosphere Data Assimilation in the ECMWF NWP System

Evaluation and assimilation of ATMS data in the ECMWF system

Assimilation of altimeter data in the ECMWF ocean analysis system 3

The latest version of the ECMWF ocean analysis system was recently introduced into operational use. This not only provides initial conditions for the monthly and seasonal forecast systems but also creates a historical reanalysis. For the first time, altimeter data are used in the ECMWF operational ocean analysis. However, making good use of altimetric sea level information was not easy and seve...

4D-Var Data Assimilation for Navy Mesoscale NWP

The long-term goal of this Rapic Transition Process (RTP) project is to provide the warfighter with superior battlespace environmental awareness in terms of high fidelity four-dimensional (4D) depiction of the regional/mesoscale atmospheric states. This situational awareness is a key aspect of information superiority in the DoD’s strategic plan to ensure battlespace dominance in the 21st centur...
