Iris is a powerful, format-agnostic, community-driven Python library for analysing and visualising Earth science data
Table of contents
Iris implements a data model based on the CF conventions giving you a powerful, format-agnostic interface for working with your data. It excels when working with multi-dimensional Earth Science data, where tabular representations become unwieldy and inefficient.
CF Standard names, units, and coordinate metadata are built into Iris, giving you a rich and expressive interface for maintaining an accurate representation of your data. Its treatment of data and associated metadata as first-class objects includes:
- a visualisation interface based on matplotlib and cartopy,
- unit conversion,
- subsetting and extraction,
- merge and concatenate,
- aggregations and reductions (including min, max, mean and weighted averages),
- interpolation and regridding (including nearest-neighbor, linear and area-weighted), and
- operator overloads (
A number of file formats are recognised by Iris, including CF-compliant NetCDF, GRIB, and PP, and it has a plugin architecture to allow other formats to be added seamlessly.
Building upon NumPy and dask, Iris scales from efficient single-machine workflows right through to multi-core clusters and HPC. Interoperability with packages from the wider scientific Python ecosystem comes from Iris' use of standard NumPy/dask arrays as its underlying data storage.
The documentation for Iris is available at https://scitools.org.uk/iris/docs/latest, including a user guide, example code, and gallery.
The easiest way to install Iris is with conda:
conda install -c conda-forge iris
Detailed instructions, including information on installing from source, are available in INSTALL.
