PhenoFlex_fixedDynModelwrapper
Description
PhenoFlex wrapper function for the 'phenologyFitter' function using the GDH heat accumulation model and parameters of the dynamical model fixed. The default values for the dynamic model parameters are from the excel file with unknown origin.
Usage
PhenoFlex_fixedDynModelwrapper(
x,
par,
A0 = 139500,
A1 = 2.567e+18,
E0 = 4153.5,
E1 = 12888.8,
slope = 1.6,
Tf = 4
)
