Pull Request Overview
This PR introduces a new reduce transform for EVA that performs generic reduction operations on DataArray objects within DataCollections. The transform supports common statistical operations (mean, sum, min, max, std) and an identity operation for applying mask/squeeze transformations without reduction.
Key Changes:
- Added a new reduce transform module with support for dimensional reduction operations
- Implemented optional fill value masking and vertical dimension squeezing
- Included comprehensive documentation with YAML configuration examples
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
