Crowd-Sourced Human Weather- and Impact-Reports in Austria – a crucial support to mitigate extreme weather- and climate- impacts?

Vortragender: Thomas Krennert (GeoSphere Austria)

Governments and civil authorities struggle with mounting socio-economic challenges caused by extreme weather and climate impacts. In the context of real-time warnings and future risk assessments, robust data on weather and climate related hazards and damages are essential. Since 2020, Austria's national weather service, GeoSphere Austria (formerly ZAMG), has compiled a database of About 120,000 human weather and impact reports, facilitated through the web-app wettermelden.at. Since weather stations cannot detect hazards like flooding, wind damage or similar, these impact observations provide a valuable “ground-truth” data source. Utilizing weather- and impact-reports a real time feedback loop between disseminated weather warnings and impact reports

from voluntary observers is established - an important capability for GeoSphere as a key advisor within the Austrian National Crisis and Disaster Management SKKM. Moreover, these reports contribute to forensic damage assessments following extreme weather events and provide valuable data for climate impact research.

With the Trusted Spotter Network Austria (TSN), GeoSphere offers a comprehensive training program for voluntary weather enthusiasts. Through this program, fully trained "Trusted Spotters" enhance the accuracy and reliability of their reports.

Das Kolloquium wird in Zusammenarbeit mit dem Forschungsverbund VINAR und der GeoSphere Austria (früher ZAMG) durchgeführt.
