Getting Started

Installation

Important

To install this package, ensure that you are using one of the supported Python versions

Install sdf-xarray from PyPI with:

pip install sdf-xarray

or download this code locally:

git clone --recursive https://github.com/epochpic/sdf-xarray.git
cd sdf-xarray
pip install .

Note

When loading SDF files, variables related to boundaries, cpu and output file are excluded as they are problematic. If you wish to load these in please use the Loading raw files approach.

Tip

All code examples throughout this documentation are visualised using Jupyter notebooks so that you can interactively explore xarray.Dataset objects. To do this on your machine make sure that you have the necessary dependencies installed:

pip install "sdf-xarray[jupyter]"

Usage

sdf-xarray is a backend for xarray, and so is usable directly from xarray. There are several ways to load SDF files:

• To load a single file, use xarray.open_dataset.

• To load multiple files, use sdf_xarray.open_mfdataset or xarray.open_mfdataset.

• To access the raw contents of a single SDF file, use sdf_xarray.sdf_interface.SDFFile.

Loading single files

import xarray as xr

xr.open_dataset("tutorial_dataset_1d/0010.sdf")
