ice_flow_rate_across_grounding_line() void pism::ice_flow_rate_across_grounding_line ( const array::CellType1 &  cell_type, const array::Staggered1 &  flux, double  unit_conversion_factor, array::Scalar &  output  ) Compute the ice flow rate across the grounding line, adding to output to accumulate contributions from multiple time steps. When unit_conversion_factor is 1 the units of output are "m^3 / s". Negative flux corresponds to ice moving into the ocean, i.e. from grounded to floating areas. (This convention makes it easier to compare this quantity to the surface mass balance or calving fluxes.) Different choices of the unit_conversion_factor make it possible to use this in the grounding line flux diagnostic (in kg / (m^2 s)), the volume flow rate diagnostic (in m^3 / s), or the mass flow rate diagnostic (in kg / s). Compute the ice flow rate across the grounding line over a time step, adding to output to accumulate contributions from multiple time steps. The units of output are "kg". Negative flux corresponds to ice moving into the ocean, i.e. from grounded to floating areas. (This convention makes it easier to compare this quantity to the surface mass balance or calving fluxes.)
