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 (4x4km) via a data API For select hazards, historic and probabilistic events sets, for past, present and future climate exist at distinct time horizons. You will find a repository containing scientific peer-reviewed articles that explain software components implemented in CLIMADA here.

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 (3.9+) version of CLIMADA - please see here for backward compatibility with the MATLAB version.

Getting started#

CLIMADA runs on Windows, macOS and Linux. The released versions of CLIMADA are available from conda-forge. Use the Mamba package manager to install it:

mamba install -c conda-forge climada

It is highly recommended to install CLIMADA into a separate Conda environment. See the installation guide for further information.

Follow the tutorials in a Jupyter Notebook to see what can be done with CLIMADA and how.


The online documentation is available on Read the Docs.The documentation of each release version of CLIMADA can be accessed separately through the drop-down menu at the bottom of the left sidebar. Additionally, the version ‘stable’ refers to the most recent release (installed via conda), and ‘latest’ refers to the latest unstable development version (the develop branch).
