Integration of quantitative analysis and local community involvement for wildfire risk mapping: a case study from an Alpine valley

This work describes a database on holdover times of lightning-ignited wildfires (LIWs). Holdover time is defined as the time between lightning-induced fire ignition and fire detection. The database contains 42 datasets built with data on more than 152,375 LIWs from 13 countries extending from 1921 to 2020. This database is the first freely-available, harmonized, and ready-to-use global source of holdover time data, which may be used to investigate LIWs and model the holdover phenomenon.
