This is a page shows the Objectives and Accomplishments of the Ensemble Testbed for AOP10 ending February 28, 2011.

Objectives — AOP10

In response to the US NWS operational centers move toward ensemble-based probabilistic forecasting, the DTC established the DTC Ensemble Testbed to provide an environment in which extensive testing and evaluation of ensemble-related techniques developed by the NWP community can be conducted such that the results are immediately relevant to the operational centers (NCEP and AFWA).

When fully developed, Ensemble Testbed activities will involve maintaining and supporting community codes, as well as conducting extensive testing and evaluation of promising new capabilities and techniques that have been incorporated into these community codes.

This is a page shows the Objectives and Accomplishments of the Ensemble Testbed for AOP12 ending February 28, 2013.

Objectives — AOP12

The DTC Science Advisory Board, assists the DTC Director in shaping the strategic direction and objectives for the DTC. In response to the DTC Science Advisory Board Governance, the primary goal of this task in AOP 2012 is to provide an environment in which extensive testing and evaluation of ensemble-related techniques developed by the NWP community can be conducted such that the results are immediately relevant to the operational centers (e.g., NCEP and AFWA). There are two ensemble systems that this task will focus on in AOP 2012: the NCE NCEP Short Range Ensemble Forecast (SREF) and a developmental Hurricane-WRF (HWRF) ensemble, on the 27km basin-scale domain. While work on the NCEP SREF will be focused on improved forecasting, work on the HWRF ensemble will be focused on its use as a component of a GSI-Hybrid data assimilation scheme.

When fully developed, Ensemble Testbed activities will involve maintaining and supporting community codes, as well as conducting extensive testing and evaluation of promising new capabilities and techniques that have been incorporated into these community codes.
