The first index that measures extreme meteorological events

and detects climate change trends

In recent decades there has been an increase in the frequency of extreme meteorological events. The E3CI Index returns Copernicus ERA5-based statistics on the occurrence and intensity of meteorological events, providing data that are immediately useful for identifying trends and formulating forecasts on a national, regional and provincial scale.

How is Italy faring?

In the paper “How is Italy faring?”, starting from the data of the European Extreme Events Climate Index, the extraordinary meteorological events that characterized Italy in the hydrological year from September 2022 to August 2023 are analyzed, quantified, and monitored. The analysis not only allows us to better understand the magnitude of certain phenomena but also to identify trends and provide scientific and visual support to what is happening at the climatic level.

Narrating extreme events

Discover how the data from the Index can enrich and support the scientific or journalistic narrative of extreme events.

Through the Index, you can access an extensive amount of data on the trends of meteorological events from 1980 onwards. You can customize your search and generate output—data and infographics—for analysis based on specific needs, contexts, or climatic dynamics. For this reason, it is particularly useful for media professionals and those involved in scientific communication in drafting articles, long-form pieces, studies, and in-depth analyses.
