get_snow_accumulation() void pism::surface::PDDMassBalance::get_snow_accumulation ( const std::vector< double > &  T, std::vector< double > &  P  ) virtual Extract snow accumulation from mixed (snow and rain) precipitation using the temperature time-series. Uses the temperature time-series to determine whether the precipitation is snow or rain. Rain is removed entirely from the surface mass balance, and will not be included in the computed runoff, which is meltwater runoff. There is an allowed linear transition for Tmin below which all precipitation is interpreted as snow, and Tmax above which all precipitation is rain (see, e.g. [Hock2005b]). Sets P[i] to the solid (snow) accumulation rate. Parameters [in,out] P precipitation rate (array of length N) [in] T air temperature (array of length N) [in] N array length Implements pism::surface::LocalMassBalance.
