Regression tests for NOAA's weather model code (NOAA)

NOAA Unified Forecast System Weather Model (UFS-WM) Regression Tests
atmosphere NOAA NOAA active
In plain English

What it measures. A suite of automated tests and their results, used to confirm that changes to NOAA's main weather model don't break existing capabilities.

How it's made. NOAA maintains these regression tests for the UFS Weather Model, currently numbering 123 cases covering global, hurricane, and other forecast applications.

How & where you'd use it. It is purely a software-quality resource for model developers, ensuring code stays reliable; it has no direct everyday use.

Official description

The Unified Forecast System (UFS) is a community-based, coupled, comprehensive Earth Modeling System. The ufs-weather-model (UFS-WM) is the model source of the UFS for NOAA’s operational numerical weather prediction applications. The UFS-WM Regression Test (RT) is the testing software to ensure that previously developed and tested capabilities in UFS-WM still work after code changes are integrated into the system. It is required that UFS-WM RTs are performed successfully on the required Tier-1 platforms whenever code changes are made to the UFS-WM. The results of the UFS-WM RTs are summarized in log files and these files will be committed to the UFS-WM repository along with the code changes. Currently, the UFS-WM RTs have been developed to support several applications targeted for operational implementations including the global weather forecast, subseasonal to seasonal forecasts, hurricane forecast, regional rapid refresh forecast, and ocean analysis. At this time, there are 123 regression tests to support the UFS applications. The tests are evolving along with the development merged to the UFS-WM code repository. The regression test framework has been developed in the UFS-WM to run these tests on tier-1 supported systems. Each of the regression tests require a set of input data files and configuration files. The configuration files include namelist and model configuration files residing within the UFS-WM code repository. The input data includes initial conditions, climatology data, and fixed data sets such as orographic data and grid specification data. In addition, the r
