v26.5.0 (2026-05-13)
This release brings a host of new diagnostics, such as impact-based diagnostics for wind and rain, and plotting of observations from the Cardington observation site.
Existing diagnostics have been improved, with ML and ensemble data now loading more reliably, and plots have had various visual enhancements. A big change has been to switch the order of difference comparisons, so that now the control is subtracted from the experiment, rather than the other way around. This should make it easier to tell the direction of any bias.
To view all of these diagnostics, the web interface produced by the workflow has been overhauled, adding a search, filtering via dropdowns, and pop-out plot windows. Please send us your thoughts on the new web interface, so we can continue making it more usable!
There are many more fixes and improvements. Please visit metoffice.github.io/CSET/changelog for the full details.
