step() virtual Changes pism::surface::LocalMassBalance::step ( const DegreeDayFactors &  ddf, double  PDDs, double  ice_thickness, double  old_firn_depth, double  old_snow_depth, double  accumulation  ) pure virtual Take a step of the PDD model. Parameters [in] ddf degree day factors [in] PDDs number of positive degree days during the time step [K day] [in] old_firn_depth firn depth [ice equivalent meters] [in] old_snow_depth snow depth [ice equivalent meters] [in] accumulation total solid (snow) accumulation during the time-step [ice equivalent meters] Implemented in pism::surface::PDDMassBalance.
