Welcome
The Unified Forecast System (UFS) is a community-based, coupled, comprehensive Earth modeling system. NOAA’s operational model suite for numerical weather prediction (NWP) is quickly transitioning to the UFS from a number of different modeling systems. The UFS enables research, development, and contribution opportunities within the broader Weather Enterprise (including government, industry, and academia). For more information about the UFS, visit the
UFS Portal
Description
The UFS Unified Workflow (UW) project is a
collaboration
between EPIC and several community partners
, including NOAA Global Systems Laboratory (GSL) and the University of Colorado Cooperative Institute for Research in Environmental Sciences (CU/CIRES), who share a common goal of building software that will unify UFS workflows. The team’s
uwtools
software is a modern, open-source Python package that helps automate common tasks needed for many standard NWP workflows. It also provides drivers to automate the configuration and execution of UFS components, providing flexibility, interoperability, and usability to various UFS Applications. The
Unified Workflow (UW) tools
are accessible from both a command-line interface (CLI) and a Python API. The CLI automates many core NWP workflow functions; the API supports all CLI operations and additionally provides access to in-memory objects to facilitate more novel use cases. These options allow users to integrate the package into pre-existing bash and Python scripts, in addition to providing some handy tools for use in day-to-day work with NWP systems.
Getting Started
The recommended UW tools installation mechanism uses the Python package and virtual-environment manager
conda
. The
Miniforge
variant of
Miniconda
, which by default uses packages from the
conda-forge
project, is an especially useful basis for working with conda. The
UW Tools Installation Guide
provides detailed installation instructions both for users who are starting from scratch and for users with an existing conda installation on their system. Developers can refer to the
Developer Setup
chapter for instructions on creating and building a bash development shell for their
uwtools
development work.
