get_PDDs() void pism::surface::PDDMassBalance::get_PDDs ( double  dt_series, const std::vector< double > &  S, const std::vector< double > &  T, std::vector< double > &  PDDs  ) virtual Compute the expected number of positive degree days from the input temperature time-series. Use the rectangle method for simplicity. Parameters S standard deviation for air temperature excursions dt_series length of the step for the time-series T air temperature (array of length N) N length of the T array [out] PDDs pointer to a pre-allocated array with N-1 elements Implements pism::surface::LocalMassBalance.
