Various methods of processing long-term phenological series

Popis výsledku v původním jazyce

In this work we elaborated long-term phenological series with using computer tool PhenoClim. PhenoClim is software for calculating temperature tresholds (Tbase) and sum of effective units (TS) and subsequently for modeling the terms of phenophases at various experimental sites and also under future climate conditions. For evaluation the terms of phenophases of five wild shrubs from one experimental site were used. The two methods of calculation (thermal time model and method of sine wave) were tested and Tbase and TS were calculated as precise as possible. The accuracy of model were determined by statistical indicators -- RMSE (root mean square error) and R2 (coefficient of determination). Two used methods for five shrubs showed almost similar values of Tbase and TS with almost same statistical indicators. Using Tbase and TS the onset of phenophases were calculate and estimate for future climate conditions.
