T. Krennert, et al., TSN A Crowd Sourcing Standard for Impact Observations? 9/26/2017 PAGE 6/11 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 observers in Austria (~200 QC0+, ~80 QC1) Increase the number of reports / question of resources, cost-benefit ratio? Simplify reporting criteria / reporting process? Report parameters ubiquitous for Europe?

Krennert, et al., TSN A Crowd Sourcing Standard for Impact Observations? 9/26/2017 PAGE 7/11 Introducing EWOB report criteria European Weather Observer EWOB was developed by ESSL Parameters are clearly structured & well defined (Impacts) Severe event reports are automatically forwarded to the ESWD Available in more than 20 languages Most substantial coverage for impact report parameters As of now: switchover from ESWSD to EWOB for TSN Austria No precipitation Rain or Snow Choose weather type Take a picture Add other info Hail Strong Wind Whirlwinds Bad Visibility Close Lightning Flooding Fresh Snow Height Land Slide / Avalanche Other Phenomena Hail less than 1 cm Strong wind send
