The NEMO_Nowcast package is a collection of Python modules that can be used to build a software system to run the NEMO ocean model in a daily nowcast/forecast mode. Such a system typically uses as-recent-as-available forcing data or model products for open boundary conditions, river run-off flows, and atmospheric forcing.
The runs are automated using an asynchronous, message-based architecture. The Salish Sea NEMO Nowcast system is one example of a system built on this framework. That system:
obtains the forcing datasets from web services
