Getting Started

Getting Started#


  1. Familiarity with xarray, since this package is an extension of it

  2. xCDAT is distributed through the conda-forge channel of Anaconda. We recommend using Mamba (via Miniforge), a drop-in replacement of Conda that is faster and more reliable than Conda. Miniforge ships with conda-forge set as the prioritized channel. Mamba also uses the same commands and configurations as Conda, and you can swap commands between both tools.

    Follow these steps to install Miniforge (Mac OS & Linux):

    curl -L -O "$(uname)-$(uname -m).sh"
    bash Miniforge3-$(uname)-$(uname -m).sh

    Then follow the instructions for installation. We recommend you type yes in response to "Do you wish the installer to initialize Miniforge by running conda init?" to add conda and mamba to your path. Note that this will modify your shell profile (e.g., ~/.bashrc).

    Note: After installation completes you may need to type ``bash`` to restart your shell (if you use bash). Alternatively, you can log out and log back in.


  1. Create a Mamba environment from scratch with xcdat (mamba create)

    We recommend using the Mamba environment creation procedure to install xcdat. The advantage with following this approach is that Mamba will attempt to resolve dependencies (e.g. python >= 3.8) for compatibility.

    To create an xcdat Mamba environment, run:

    >>> mamba create -n <ENV_NAME> -c conda-forge xcdat
    >>> mamba activate <ENV_NAME>
  2. Install xcdat in an existing Mamba environment (mamba install)

    You can also install xcdat in an existing Mamba environment, granted that Mamba is able to resolve the compatible dependencies.

    >>> mamba activate <ENV_NAME>
    >>> mamba install -c conda-forge xcdat
  3. [Optional] Some packages that are commonly used with xcdat can be installed either in step 1 or step 2 above:

    • jupyterlab: a web-based interactive development environment for notebooks, code, and data. This package also includes ipykernel.

    • matplotlib: a library for creating visualizations in Python.

    • cartopy: an add-on package for matplotlib and specialized for geospatial data processing.


New versions of xcdat will be released periodically. We recommend you use the latest stable version of xcdat for the latest features and bug fixes.

>>> mamba activate <ENV_NAME>
>>> mamba update xcdat

To update to a specific version of xcdat:

>>> mamba activate <ENV_NAME>
>>> mamba update xcdat=<MAJOR.MINOR.PATCH>
