| GEOPOTENTIAL_METRE | gpm | geopotential energy height (geopotential specific energy) | A height proportional to the potential energy of mass (geopotential) at this height relative to the geoid. The geopotential metre varies with geodetic latitude. On <EARTH> at mid-latitudes it equals 0,98 m (approximately). |
