Xarray - N-Dimensional Labeled Arrays

Xarray provides a pandas-like experience for multidimensional data. It is the core of the Pangeo ecosystem and is essential for working with NetCDF, GRIB, and Zarr formats.

When to Use

• Working with multi-dimensional scientific data (Time, Lat, Lon, Level, Ensemble).
• Analyzing climate, weather, or oceanographic datasets (NetCDF files).
• Handling large datasets that don't fit in memory (via Dask integration).
• Performing complex broadcasting and alignment based on dimension names instead of axis indices.
• Storing metadata (units, descriptions) directly inside the data object.
• Remote sensing and geospatial imaging analysis.
