xarray-netcdf

What problem does it solve?

This Skill helps you analyze large, multi-dimensional scientific datasets stored in NetCDF/HDF5 by providing labeled array operations with lazy loading, efficient parallel computation, and standards-compliant metadata handling.

Core Features & Use Cases

• Labeled N-D data analysis: Use xarray’s named dimensions and coordinates to select, align, merge, interpolate, and compute statistics without losing semantic meaning.
• Scalable I/O with lazy Dask execution: Open and transform datasets without loading everything into RAM, then compute results when needed.
• Cloud-ready storage and interoperability: Convert NetCDF to chunked Zarr stores for faster parallel access, and write CF-compliant metadata for downstream tooling.

Use Case: You have multiple years of climate model output in NetCDF and need to compute seasonal means, anomalies, and area-weighted global averages while converting the dataset to Zarr for efficient reanalysis and sharing.

Quick Start

Use the xarray-netcdf skill to open a large NetCDF file with Dask chunking, compute a seasonal mean from a chosen variable, and write the result back with CF metadata preserved.
