Description	Studie popisuje šíření chyb v hodnotách globální radiace v růstových modelech a provádí nepřímou validaci náhradních metod výpočtu RG. (cs) The results of the recently published studies suggest that the estimated RG values are loaded with an error, which might compromise the precision of the subsequent crop model applications. Such error would then translate in the analyses based on the crop models as e.g. crop yield forecasting or climate change impact studies. Therefore a detailed analysis of the error propagation was made using two crop models i.e. CERES-Barley and CERES-Wheat. Database of meteorological data originating from 8 stations in Austria and Czech Republic was used in order to carry out the analysis. It has been found that even application of the method based on sunshine duration hours that yield the lowest bias in RGestimates significantly influences number of key crop model outputs. It has been also noted that in 5-6 seasons out 100 cases of deviation greater than +-10 % are to be expected whilst the chance of occurrence of even greater error (+-25 %) is not negligible.
