Each Physical Parameter record defines a MIP variable name, associated with a CF Standard Name. Formerly known as MIP Variables in CMIP6

| description | The phrase "integral\_wrt\_X\_of\_Y" means int Y dX. To specify the limits of the integral the data variable should have an axis for X and associated coordinate bounds. If no axis for X is associated with the data variable, or no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is air the integral is assumed to be calculated over the full depth of the atmosphere. The abbreviation "wrt" means "with respect to". Depth is the vertical distance below the surface. Preformed Salinity, S\*, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). Preformed Salinity is a salinity variable that is designed to be as conservative as possible, by removing the estimated biogeochemical influences on the sea water composition. Preformed Salinity is Absolute Salinity, S\_A (which has the standard name sea\_water\_absolute\_salinity), minus all contributions to sea water composition from biogeochemical processes. Preformed Salinity is the mass fraction of dissolved material in sea water.

There are also standard names for the precisely defined salinity quantities sea\_water\_knudsen\_salinity, S\_K (used for salinity observations between 1901 and 1966), sea\_water\_cox\_salinity, S\_C (used for salinity observations between 1967 and 1977), sea\_water\_practical\_salinity, S\_P (used for salinity observations from 1978 onwards), and sea\_water\_reference\_salinity. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea\_water\_salinity. |
