v25.7.0 (2025-07-17)

Over the last two months development of CSET has been steaming ahead. In this release we bring something for everyone.

Figures have been improves so they are better layouts, colours and titles, and use consistent units.

The output webpage now includes extra information so you can tell the provenance of the output you are looking at, and easily copy to settings into your own workflow.

There is new functionality for trimming the domain boundaries (useful for
removing regions where unphysical data exists), and new recipes for calculating summary statistics within a case, such as mean, min/max, or standard deviation.

There have been a number of fixes to how common time points are selected; this has fixed a nasty issue with the diurnal cycle being offset by an hour under certain circumstances. Wind directions are now normalised to true North/East, to allow comparison between models with different conventions.

The workflow has been streamlined, and is now faster due to using an external conda environment, and has an improved tutorial, so it is easier than ever to learn how to use it. The workflow is also easier to install; rather than having to download a separate tarball, it comes included with the cset command line.

Developers are not forgotten either, with the development environment now being setup with a single make command, and the workflow code having moved into the main CSET package for easier testing and distribution.
