Towards a New Standard in the Field of Crowd-Sourced Weather- and Impact- Observations
Reliable information about weather impacts
T. Krennert, et al., TSN – A Crowd Sourcing Standard for Impact Observations? 2/18/2018
Current Crowdsourcing-Methods in Meteorology
Crowd-sourced Measurements • Private Stations • Mobile Sensors • IOT - Internet of
Things
Data Mining in Social Media • Information
Retrieval • Word Crawling • Image Pattern
Recognition
Crowd-sourced Human Observations • Reporting apps
• Targeted Human
Assessment • Standardized
Parameters • Quality Management • Training • Collaborations

Challenges
• Comprehensive training necessary for complex ESWD thresholds
• Uncertainties regarding thresholds may lead to inhibition to report events
• Still complicated way to file reports digitally via the ESWD homepage
• Small group of trained observers in Austria (~200 QC0+, ~80 QC1)
• Increase the number of reports / question of resources, cost-benefit ratio?
• Simplify reporting criteria / reporting process? Relevant information?
• Report parameters ubiquitous for Europe?
T. Krennert, et al., TSN – A Crowd Sourcing Standard for Impact Observations? 2/18/2018
• European Weather OBserver EWOB, developed by ESSL as native app with its own DB
• Parameters are clearly structured and well defined by weather impacts
• Severe event reports are automatically forwarded to the ESWD
• Available in more than 20 languages
• Most substantial coverage for impact – report parameters

… provide feedback
• Currently, feedback to the Forecaster is often missing or not sufficient yet
• Modern communication technologies allow to close feedback-loop in real-time
• Feedback with: 1. Standardized weather- and impact observation parameters,
2. Quality controlled reports and 3. Trained observers
• Using impact obs. for verification of impact based warnings and forecasts
• National Impact-Databases: Synergies within EUMETNET activities?

Highlights
• TSN Austria – EMS best practice for reliable human crowd sourced observations
• ESWD – scientifically widely established standard of severe weather reports
• EWOB – database of standardized weather- and impact observations
• Combination of established standards of reporting parameters, QC and training
• Standardized, minimum intersecting set of reporting parameters on EU level, flexible
national parameter set
• Integration of EWOB data base within pre-existing reporting apps from European
NMHSs via API, NMHSs operate as national hubs
Invitations:
• FMI, ESSL and ZAMG started communication on standardization
• ESWD / EWOB user forum 14-15 March: open discussion on reporting parameter set
Collaboration for standardization between European NMHSs possible?
Within the EUMETNET framework?
