NCEP encourages all users to ensure their decoders are flexible and are able to adequately handle changes in content order and also any volume changes which may be forthcoming.

These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes prior to any implementations.

NWM Operational Configuration: The NWM runs ten uncoupled analyses simulations of current conditions with look-back periods ranging from 28 hours to 3 hours. Analysis and Assimilation Configurations: Standard Analysis and Assimilation The Standard Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS.

Extended Analysis and Assimilation The Extended Analysis and Assimilation configuration cycles once per day and produces an analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS.

Long-Range Analysis and Assimilation The Long-Range Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS , using higher quality precipitation data than is available to the Standard Analysis and Assimilation. Hawaii Analysis and Assimilation The Hawaii Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the Hawaii domain.

Hawaii Short-Range Open Loop The Hawaii Short-Range open loop deterministic forecast configuration is executed two times per day using the same forcing as the Hawaii Short-Range standard configuration, but drawing initial conditions from the Hawaii Open Loop Analysis and Assimilation.

This dataset can also be used in the development of end user applications which require a long baseline of data for system training or verification purposes. Currently there are three versions of the NWM retrospective dataset A year February through December retrospective simulation using version 2.

A year January through December retrospective simulation using version 2. A year January through December retrospective simulation using version 1.

Version 2. Note that no streamflow or other data assimilation is performed within any of the NWM retrospective simulations.
