The CCI Climate Analysis Toolbox (Cate) is a cloud-enabled computing environment for analysing, processing and visualising all ESA Climate Change Initiative datasets. Cate works by mashing ECV data and other data sources into a common data model. Users operate on this model, then analyse, process, and visualise the results.


Cate comprises various user interfaces:

Cate can be used in two ways: (1) as a service provided through ESA or (2) in standalone mode on your own computer. The Software as a service (SaaS) can be found here. It is currently made available to testers only, while the user experience is being improved.

In standalone mode, Cate can be installed as a Python package in the Conda package repository. Since it is completely open source, Cate can be installed from Cate’s GitHub repository.


The Toolbox documentation includes a Quick Start to help you get going with the Command Line Interface and a User Manual that describes each of the user interfaces. It also comprises technical details such as an Architecture Description and API Reference.


Cate reads the CCI ECV datasets directly from the Open Data Portal. You can also open your own data sources such as NetCDF files and ESRI shapefiles.
