__RADOLAN (radolan) radar precipitation analysis (by DWD):__ Radar-derived precipitation analysis, online calibrated to ground observations. Available (nearly) immediately. 1-h precipitation sums. Undefined in case of missing radar data, therefore not suitable as estimate for long-term precipitation sums. --- //[[treinhar@meteo.uni-koeln.de|Thorsten Reinhardt]] 2006/11/21 18:00//
