v3.0.1

This release includes enhancements and bug fixes that primarily impact users working with high-frequency EAMxx output, polar maps, and high-resolution streamflow diagnostics, as well as those affected by bugs introduced in the major v3 release. Notable updates include tropical_subseasonal set support for eamxx, improved regridding accuracy through explicit 2D masking, dynamic-resolution support in streamflow diagnostics, and the addition of new variables. Visualization layout fixes are also included for improved PDF output handling.

v3.0.0 Modernization with Xarray and xCDAT

What's Changed

v3.0.0 marks a major milestone after nearly two years of work by the core development team. This release introduces a completely new back-end, replacing CDAT with Xarray and xCDAT. Due to the significant scale of code changes, this has been incremented as a major release. The user-facing API for running E3SM Diagnostics remains backward-compatible between v2 and v3.

The modernization improves performance, usability, and maintainability, paving the way for future enhancements to E3SM development. The refactored codebase is now more robust and extensively covered by unit tests, setting a solid foundation for ongoing testing and development.

This release also includes several new enhancements including support for more EAMxx variables, standardization of regridding with xESMF's conservative_normed method, and improving diagnostic run performance by skipping unnecessary regridding of datasets with the same lat-lon grid.

We are excited to share this release with the E3SM community and remain committed to continuously improving the software!

Enhancements

• Add support for more EAMxx variables by @chengzhuzhang, @tomvothecoder, and @czender in #880
• Standardize regridding to conservative_normed by @tomvothecoder and @chengzhuzhang in #940
• Improve diagnostic run performance by skipping regridding for two datasets on same lat-lon grids by @chengzhuzhang in #959
• Revamp logging to improve readability and output E3SM diagnostic configuration, prevent duplicate log messages, and save complete console output to log file in prov directory by @tomvothecoder in #924
• Make viewer accessible at the top-level of results directory by @tomvothecoder in #927

Bug Fixes

• Fix prov files not printing with links in prov index.html by @tomvothecoder in #937

Refactor and testing

• Merge v3.0.0 development branch (cdat-migration-fy24) into main with the new Xarray/xCDAT backend by @tomvothecoder, @chengzhuzhang, @forsyth2, and @xylar in #902

DevOps

• Replace deprecated SciPy cwt with PyWavelets cwt by @tomvothecoder, @chengzhuzhang, and @whannah1 in #913
• Make scipy a base dependency in ci.yml and dev.yml by @tomvothecoder in #905
• Constrain dask !=2024.12.0,!=2024.12.1 for performance by @tomvothecoder in #926

v2.12.1 A Fond Farewell to CDAT

As we release version v2.12.1 of E3SM Diags, we would like to take a moment to acknowledge and express our gratitude to the developers and contributors from the CDAT (Climate Data Analysis Tools) community. Over the years, CDAT has been an invaluable tool for our development and analysis processes. This release marks a milestone, as it will be the final version of E3SM Diags that includes a dependency on CDAT.

Looking ahead, E3SM Diags will transition to utilizing xarray/xCDAT tools, which align with our future goals and enhances the performance and usability of our software. We are committed to ensuring a smooth transition for our users and will provide backward compatibility in upcoming releases.
