| Definition | "Sea surface height" is a time-varying quantity. "Height_above_X" means the vertical distance above the named surface X. "Mean lower low water" is the arithmetic mean of the lower low water height of each tidal day observed at a station over a Tidal Datum Epoch, which is a period of time that is usually greater than 18.6 years to include a full lunar cycle. Tidal datums in certain regions with anomalous sea level changes may be calculated using a shorter, or modified, Tidal Datum Epoch (e.g. 5 years). To specify the tidal datum epoch to which the quantity applies, provide a scalar coordinate variable with standard name reference_epoch. | ||
