 There are two parts to the Redi/GM parameterization of geostrophic
-eddies. The first, the Redi scheme \citep{re82}, aims to mix tracer properties along isentropes
-(neutral surfaces) by means of a diffusion operator oriented along the
-local isentropic surface. The second part, GM \citep{gen-mcw:90,gen-eta:95}, adiabatically
