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 is 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.

About the project:
Sectors like agriculture, health and water resources want information on how climate extremes affect their operations. But information on extremes is often buried in meteorological data and is not directly applicable to specific sectors. Climpact has been developed to address these concerns. The Climpact open source package for R reads in meteorological data (daily minimum and maximum temperatures, as well as daily precipitation) and delivers the frequency, duration and magnitude of various climate extremes that are directly relevant to each sector. Indices calculated by Climpact are available at both monthly and annual timescales.
