1. UERRA User Workshop Toulouse, 4 th Feb 2016 Questions to the users

2. Applications: energy (wind, solar, demand), power- plant cooling, hydrological applications, insurance, transport, defence, agriculture and forestry, climate change impact assessment, model evaluation, atmospheric physics Resolution higher than ERA-Interim needed. Why you are interested in high resolution regional reanalyses?

3. - Wind speed (gusts) 10-200m, - precipitation, 2m temperature, solar radiation, - humidity, water vapour, - soil moisture for agriculture, - snow parameters, - cloud cover, cloud top/base, (albedo maybe?) - 3D fields to initialize/compare/run models (RCM, high-res, seasonal, hydrological etc) Priority parameters?

4. Scales of interest I1) Temporal scale of phenomenon of interest? Hourly, 6h, daily, monthly, multi-annual Some real-time applications Some applications request > 30 years I2) Spatial scale of phenomenon of interest? Desirable: 100m,1-4 km, Minimum: 10 km,11 km, 25 km I3) Verification on local, regional, national, or European scale? all

5. Scientific Questions Is there anything else you would like to see? For what purpose will you want to use the reanalysis data? How can the data be validated so that you have confidence in it? What validation techniques are you already using? Are there any issues with interpreting/applying validation results?

6. Questions related to the visualisation tools V1) Do you need web-based tools like ADAGUC/climate4impact? V2) Are you developing tools yourself that might be shared? V3) Are there specific visualisation requirements related to your application that you would like to see implemented?

7. Technical questions T1) R scripts ok? T2) Git/github ok?

8. Verification questions V1) Scores (...) of priority? Mean, min, max, Verification scores (“accuracy is important”) highest resolution - is noise taking over? V2) Ensemble measures? Spread, median V3) Verification on local, regional, national, or European scale?

9. Your history? H1) Which data sources do you use now? ERA-Interim, station data, satellite data, radar H2) How long time series you use now? H3) Which uncertainties?

10. Support? S1) Which support would be paradise? S2) Which kind of support is absolutely essential for you? Documentation, user guides (e.g., on spin-up of precip in forecast), papers, FAQs

11. Examples for application Wanted?
