⚠️ Breaking Change in v0.1.0

v0.1.0 includes a major refactor with breaking API changes.

• Migration steps: docs/migration-guide-v0.1.0.md
• Canonical install options (prerelease vs stable): docs/installation.md

Xee: Xarray + Google Earth Engine

Xee is an Xarray backend for Google Earth Engine. Open ee.Image / ee.ImageCollection objects as lazy xarray.Datasets and analyze petabyte-scale Earth data with the scientific Python stack.

Install

For the latest v0.1.0 prerelease:

pip install --upgrade --pre xee

For all installation paths (including stable line and conda), see docs/installation.md.

Minimal example

import ee
import xarray as xr
from xee import helpers

# Authenticate once (on a persistent machine):
#   earthengine authenticate

project = 'PROJECT-ID'  # Set your Earth Engine registered Google Cloud project ID
# Initialize (high-volume endpoint recommended for reading stored collections)
ee.Initialize(project=project, opt_url='https://earthengine-highvolume.googleapis.com')

# Open a dataset by matching its native grid
ic = ee.ImageCollection('ECMWF/ERA5_LAND/MONTHLY_AGGR')
grid = helpers.extract_grid_params(ic)
ds = xr.open_dataset(ic, engine='ee', **grid)
print(ds)

• Concepts (grid params, CRS, orientation)
• User Guide (workflows)

Features

• Lazy, parallel pixel retrieval through Earth Engine
• Flexible output grid definition (fixed resolution or fixed shape)
• CF-friendly dimension order: [time, y, x]
• Plays nicely with Xarray, Dask, and friends
