Detailed Description

The PDD scheme described by Formula (6) in [Faustoetal2009] requires special knowledge of latitude and mean July temp to set degree day factors for Greenland.

These formulas are inherited by [Faustoetal2009] from [Greve2005geothermal]. There was, apparently, tuning in [Greve2005geothermal] which mixed ice dynamical ideas and surface process ideas. That is, these formulas and parameter choices arise from looking at margin shape. This may not be a good source of PDD parameters.

This may become a derived class of a LocationDependentPDDObject, if the idea is needed more in the future.

		PetscInt	j,
		PetscScalar	,
		PetscScalar	lat,
		PetscScalar	,
		DegreeDayFactors &	ddf
	)		[virtual]

If this method is called, it is assumed that i,j is in the ownership range for IceModelVec2S temp_mj.

PetscErrorCode update_temp_mj	(	IceModelVec2S *	surfelev,
		IceModelVec2S *	lat,
		IceModelVec2S *	lon
	)		[virtual]

Updates mean July near-surface air temperature.

Unfortunately this duplicates code in PA_SeaRISE_Greenland::update();
