xCDAT

xCDAT (Xarray Climate Data Analysis Tools) is an extension of xarray for climate data analysis on structured grids. It serves as a modern successor to the Community Data Analysis Tools (CDAT) library.

Project Motivation

• xCDAT is an extension of Xarray for climate data analysis on structured grids, a modern successor to the Community Data Analysis Tools (CDAT) library
• Aims to provide features and utilities for simple and robust analysis of climate data

Features

• Extension of `xr.open_dataset()` and `xr.open_mfdataset()` with post-processing options
• Generate missing bounds, center time coords, convert lon axis orientation
• Geospatial weighted averaging
• Temporal averaging, climatologies, departures
• Robust handling of CF metadata (via cf_xarray, CF Convention)
• Robust handling of dataset bounds (e.g., adding missing bounds)
• Horizontal structured regridding (extension of xESMF and Python port of regrid2)
• Vertical structured regridding (extension of xGCM)

Projects Using xCDAT

• Production usage in E3SM Diagnostics, PCMDI Metrics Package (PMP), and E3SM Unified
