Oct 1, 2025October 2025 performance summary for Ouranosinc/xclim: Delivered targeted improvements that enhance data quality, reproducibility, and maintainability. Implemented a more accurate relative humidity calculation using the WMO equation with configurable handling of invalid values, fixed history logging when as_dataset is enabled to ensure correct history attribution and top-entry ordering, and corrected vapor_pressure documentation to reflect the true calculation. Updated changelogs and docs to reflect changes. These changes reduce misreporting, increase trust in climate diagnostics, and demonstrate proficiency with Python scientific stack, data processing, and documentation workflows.

May 1, 2025May 2025: Key bug fixes and feature extension for Ouranosinc/xclim focused on correctness, robustness, and cross-variable unit handling. Highlights include corrected event start calculations for multi-dimensional conditions with cftime inputs (vectorized deltas) with tests across configurations; robustness improvements ensuring no-data scenarios yield zero and data validity checks for masking invalid results; and extension of convert_units_to to operate on xarray.Dataset and xarray.DataTree with related tests and changelog updates. Result is more reliable indicator computations, reduced false positives/negatives in no-data or complex multi-variable contexts, and streamlined unit-conversion workflows across datasets and nodes.
