| Description
| - Příspěvek srovnávává sedm metod pro stanovení denní sumy globální radiace v podmínkách střední Evropy, kdy jejich empirické koeficienty byly převzaty z předchozích studií. Statistické vyhodnocení výsledků využívající srovnání s naměřenými hodnotami vyhodnotilo jako nejperspektivnější metodu Angström-Prescotta (1940) a a metodu Klabzuba et al. (1999) pro období duben až srpen. (cs)
- Seven methods for estimating daily global radiation, RG, have been tested in the Central Europe case study area (lowlands of Austria and the Czech Republic) assuming that no data for parameterization are available, i.e. all empirical coefficients required by the selected methods were derived from previously published studies. Variability explained, root mean square error (RMSE) and mean bias error (MBE) indicates that the highest precision is reached when sunshine duration is used as predictor. The Angström-Prescott (1940) method, i.e. Eq. (1), explains 96% of the RG variability with the RMSE value (annual mean) equaling to 1.6 MJ.m-2.day- 1 and MBE being 0.1 MJ.m-2.day- 1. Generally, this method was found superior to all tested methods. If there are no reliable estimates of the empirical coefficients necessary for Eq. (1) available, the method proposed by Klabzuba et al. (1999), i.e. Eq. (2), was found to be satisfactory from April to August. If there are no sunshine duration data available, the form
