Data (do not treat the files for too precise):

• Data is from forecast systems, mainly GFS (Global Forecast System) (retrieved via wetterzentrale.de and wetteronline.de), ALADIN-AUSTRIA and COSMO-EU (retrieved via ZAMG Austria and Thomas Haiden, ZAMG: Meteorologische Analyse des Niederschlags von 22.-25. Juni 2009^{[dead link]}) - you will find an analysis at the latter about forecast-modelling differing to measured INCA Analysesystem (ZAMG) data
• all scales converted to gray/redscale, overlayed by simply adding values of daily rain amount, dividing by number of days, so grayscale will follow approximatly: black ~ 200 mm * dayintervall
• bitmaps overlayed by File:Europe political chart complete blank.svg, manually adjusted (it is not exactly same projection)
