CLIMADA in Python

Project description

DOI Build Status Documentation build status


CLIMADA stands for CLIMate ADAptation and is a probabilistic natural catastrophe impact model, that also calculates averted damage (benefit) thanks to adaptation measures of any kind (from grey to green infrastructure, behavioural, etc.).

As of today, CLIMADA provides global coverage of major climate-related extreme-weather hazards at high resolution via a data API, namely (i) tropical cyclones, (ii) river flood, (iii) agro drought and (iv) European winter storms, all at 4km spatial resolution - wildfire to be added soon. For all hazards, historic and probabilistic event sets exist, for some also under select climate forcing scenarios (RCPs) at distinct time horizons (e.g. 2040). See also papers for details.

CLIMADA is divided into two parts (two repositories):

  1. the core climada_python contains all the modules necessary for the probabilistic impact, the averted damage, uncertainty and forecast calculations. Data for hazard, exposures and impact functions can be obtained from the data API. Litpop is included as demo Exposures module, and Tropical cyclones is included as a demo Hazard module.
  2. the petals climada_petals contains all the modules for generating data (e.g., TC_Surge, WildFire, OpenStreeMap, ...). Most development is done here. The petals builds-upon the core and does not work as a stand-alone.

It is recommend for new users to begin with the core (1) and the tutorials therein.

This is the Python (3.8+) version of CLIMADA - please see for backward compatibility (MATLAB).

Getting started

CLIMADA runs on Windows, macOS and Linux. It can be installed from sources or - in case of climada_python - directly with pip. See the installation guide for instructions.

Follow the tutorial climada_python-x.y.z/doc/tutorial/1_main_climada.ipynb in a Jupyter Notebook to see what can be done with CLIMADA and how.


Documentation is available on Read the Docs:

Note that all the documentations has two versions,'latest' and 'stable', and explicit version numbers, such as 'v3.1.1', in the url path. 'latest' is created from the 'develop' branch and has the latest changes by developers, 'stable' from the latest release. For more details about documentation versions, please have a look at here.

To contribute follow these steps:

  1. Fork the project on GitHub.
  2. Create a local clone of the develop branch (git clone -b develop)
  3. Install the packages in climada_python/requirements/env_climada.yml and climada_python/requirements/env_developer.yml.
  4. Make well commented and clean commits to your repository.
  5. Make unit and integration tests on your code, preferably during development.
  6. Perform a static code analysis of your code with CLIMADA's configuration .pylintrc.
  7. Add your name to the AUTHORS file.
  8. Push the changes to GitHub (git push origin develop).
  9. On GitHub, create a new pull request onto the develop branch of CLIMADA-project/climada_python.

See our developer guide for more information.
