Did you know?: Community Workflow for the Limited Area Model Version of the FV3

Summer 2020

A workflow enabling users to run the atmospheric component of the Unified Forecast System
regional configuration (FV3-LAM) in an end-to-end capacity will soon be available to the broader
community. This community workflow is the result of a coordinated effort between EMC, GSL,
and DTC. Components of the workflow include experiment generation, Rocoto XML file
generation, and the scripts necessary to run pre-processing, model integration, and post-
processing. Collaboration across multiple labs fostered the development of a user-friendly,
modular system, allowing users to run their experiments in either a research/community mode
or in an NCEP Central Operations (NCO)-compliant environment, reproducing variable names
and directory structures used in operations at NCEP. Multiple computing platforms, external
model data sources, and CCPP physics suites are supported, with pre-defined domains already
provided for the user to choose from. The option to create a user-defined domain is also
available. The ultimate goal of the FV3-LAM community workflow is to support the general
research community, as well as facilitating research-to-operations by offering developers the
opportunity to test innovations within an NCO experiment environment to ease operational
transitions of model code at NCEP.
