get_PDDs() virtual void pism::surface::LocalMassBalance::get_PDDs ( double  dt_series, const std::vector< double > &  S, const std::vector< double > &  T, std::vector< double > &  PDDs  ) pure virtual Count positive degree days (PDDs). Returned value in units of K day. Inputs T[0],...,T[N-1] are temperatures (K) at times t, t+dt_series, ..., t+(N-1)dt_series. Inputs t, dt_series are in seconds. Implemented in pism::surface::PDDMassBalance, and pism::surface::PDDrandMassBalance.
