ESRL/PSD Seminar Series

The new FV3GFS with 'replay' capability.

Jeffrey Whitaker

Abstract

The second public release of the NGGPS global model is scheduled for March 15. I will go over the features of the new release, including the addition of 'replay' capability. Replay is a method for forcing a model run to follow an observed trajectory. It is similar in spirit to nudging, but without some of the undesirable damping properties. If the forecast model is identical to that used in the data assimilation cycle, replay exactly reproduces the analyses that are being 'replayed' to. Some potential applications of replay will be discussed that may be of interest to PSL.
