Altitude reference #5

Altitude reference (geoid or elipsoid)

En parlant de mapping; il me semble que les altitudes dans InitMIP devait etre donnée par rapport à l'ellispoid; par default les altitudes doievnt venir de BedMachine et etre par rapport au geoid; donc potentiellement il faudrait corriger bedrock, zs,et zb.... A verifier

If Fabien comments is true, we need to retreive the goid used in bedmachine and add it in pp to the altitude variables only for ISMIP6 gridded output I think.

For ISMIP6 experiment it has been added to global attributes that the reference is against the geoid. We keep the issue open as this is not a satisfactory solution => need to read and output ellipsoid in Elmer/Ice and add it to zb and zs variable in output.
