Unified Workflow Tools as a Framework for UFS Applications (Invited Presentation)

The Unified Workflow Tools package, uwtools, now boasts drivers for a variety of UFS components, including: the ufs-weather-model and several of its coupled configurations UFS_Utils, the Unified Post Processor (UPP); Joint Effort for Data assimilation Integration (JEDI) components, and the Model for Prediction Across Scales (MPAS). It also offers an option to build your own driver for execution via the uwtools framework. All drivers are configured with a schema-checked YAML language that is well-documented and verified upon driver instantiation to help users more easily and reliably work with Earth prediction systems. The uwtools package also supports a YAML interface to the Rocoto workflow manager, simplifying the creation of workflows tying together multiple components.

The uwtools package is now fully integrated with the MPAS App developed by NOAA’s Global Systems Laboratory (GSL), the UFS Short Range Weather (SRW) App, the UFS Land Data Assimilation (DA) App, and the NOAA GSL Federated Workflow. From this integration work has emerged best-practices patterns for leveraging uwtools in a variety of applications. As additional systems such as the NOS-developed UFS Coastal Application and the UFS Subseasonal-to-Seasonal Application begin to adopt uwtools, and the currently supported applications begin to advance toward fully-cycled data assimilation workflows, we expect to see a reduction of repetitive code across applications and use of common idioms that will benefit the entire UFS Community.

This talk will introduce ways in which you can start using uwtools to help increase your productivity and advance your science surrounding Earth prediction systems.
