Air pressure at sea level is the quantity often abbreviated as MSLP or PMSL. Air pressure is the force per unit area which would be exerted when the moving gas molecules of which the air is composed strike a theoretical surface of any orientation. "Mean sea level" means the time mean of sea surface elevation at a given location over an arbitrary period sufficient to eliminate the tidal signals. [CF-Standard Name]; unit: Pa

sea_water_salinity [CF-Standard Name]; unit: 0.001

sea_ice_area_fraction [CF-Standard Name]; unit: 0.01

The surface called "surface" means the lower boundary of the atmosphere. The surface temperature is the (skin) temperature at the interface, not the bulk temperature of the medium above or below. [CF-Standard Name]; unit: K

Total Water Content of Soil Layer

Comment: in each soil layer, the mass of water in all phases, including ice. Reported as 'missing' for grid cells occupied entirely by 'sea'

Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: K

Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name height, which is relative to the surface. [CF-Standard Name]; unit: m

Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: K

In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. [CF-Standard Name]; unit: kg m-2 s-1

Runoff is the liquid water which drains from land. If not specified, "runoff" refers to the sum of surface runoff and subsurface drainage. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. [CF-Standard Name]; unit: kg m-2 s-1

Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: K

"Eastward" indicates a vector component which is positive when directed eastward (negative westward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) [CF-Standard Name]; unit: m s-1

Sea Floor Depth [CF-Standard Name]; unit: m

Snow Evaporation

Comment: Water here means water in all phases. Evaporation is the conversion of liquid or solid into vapor. (The conversion of solid alone into vapor is called 'sublimation'.) In accordance with common usage in geophysical disciplines, 'flux' implies per unit area, called 'flux density' in physics. Unless indicated in the cell_methods attribute, a quantity is assumed to apply to the whole area of each horizontal grid box. Previously, the qualifier where_type was used to specify that the quantity applies only to the part of the grid box of the named type. Names containing the where_type qualifier are deprecated and newly created data should use the cell_methods attribute to indicate the horizontal area to which the quantity applies.
