European Severe Weather Database (ESWD)

The objective of the ESWD is to collect and provide detailed and quality-controlled information on severe convective storm events over Europe.

In collaboration with our partners including networks of voluntary observers, meteorological services and general public, many tens of thousands of reports have been collected.
