Use Climpact to quickly analyse climate extremes using your own weather or climate data.

Climpact is a software package to calculate climate indices that are relevant for the health, agriculture and water sectors.

The indices calculated by Climpact are derived from daily temperature and rainfall data.

Climpact allows you to calculate these indices from your own daily weather data—either plain-text point data (from a weather station, for example) or across an entire gridded NetCDF file (like climate model output).

Climpact was developed by the World Meteorological Organization's Expert Team on Sector-Specific Climate Indices (ET-SCI) to help researchers deliver useful and relevant climate information to sector users.
