Detailed Description

A class implementing a constant-in-time atmosphere model. Reads data from a PISM input file.

Definition at line 61 of file PISMAtmosphere.hh.

Constructor & Destructor Documentation

PAConstant	(	IceGrid &	g,
		const NCConfigVariable &	conf
	)		`[inline]`

	)		`[virtual]`

Adds more variable names to result (to let sub-models respect -o_size or -save_size).

Keyword can be one of "small", "medium" or "big".
