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

glacier mask, 0:no; 1:yes; unit: 0,1

"[horizontal_]divergence_of_X" means [horizontal] divergence of a vector X; if X does not have a vertical component then "horizontal" should be omitted. 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: s-1

When computing the time-mean here, the time-samples, weighted by the area of sea ice in the grid cell, are accumulated and then divided by the sum of the weights. Reported as "missing" in regions free of sea ice. Note this will be the surface snow temperature in regions where snow covers the sea ice.; unit: K

sea_ice_area_fraction [CF-Standard Name]; unit: 0-1

Mass fraction is used in the construction mass_fraction_of_X_in_Y, where X is a material constituent of Y. It means the ratio of the mass of Y to the mass of X (including Y). [CF-Standard Name]; unit: kg kg-1

"lwe" means liquid water equivalent. "Amount" means mass per unit area. The construction lwe_thickness_of_X_amount or _content means the vertical extent of a layer of liquid water having the same mass per unit area. "Water" means water in all phases, including frozen i.e. ice and snow. "Canopy" means the plant or vegetation canopy. The canopy water is the water on the canopy.[CF-Standard Name]; unit: m

"moisture" means water in all phases contained in soil. "Content" indicates a quantity per unit area. The "soil content" of a quantity refers to the vertical integral from the surface down to the bottom of the soil model. For the content between specified levels in the soil, standard names including content_of_soil_layer are used. The field capacity of soil is the maximum content of water it can retain against gravitational drainage. [CF-Standard Name]; unit: m

sea_ice_thickness [CF-Standard Name]; unit: m

sea_land_mask; unit: 0,1

The surface called "surface" means the lower boundary of the atmosphere. Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. [CF-Standard Name]; unit: m2 s-2

Mass fraction is used in the construction mass_fraction_of_X_in_Y, where X is a material constituent of Y. It means the ratio of the mass of Y to the mass of X (including Y). [CF-Standard Name]; unit: kg kg-1

Sea surface temperature is usually abbreviated as "SST". It is the temperature of sea water near the surface (including the part under sea-ice, if any), and not the skin temperature, whose standard name is surface_temperature. For the temperature of sea water at a particular depth or layer, a data variable of sea_water_temperature with a vertical coordinate axis should be used. [CF-Standard Name]; unit: K

"moisture" means water in all phases contained in soil. "Content" indicates a quantity per unit area. The "soil content" of a quantity refers to the vertical integral from the surface down to the bottom of the soil model. For the content between specified levels in the soil, standard names including content_of_soil_layer are used. [CF-Standard Name where cell method]; unit: m

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

"specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air.[CF-Standard Name]; unit: kg kg-1

The surface called "surface" means the lower boundary of the atmosphere. Unless indicated, a quantity is assumed to apply to the whole area of each horizontal grid box. The qualifier where_type specifies instead that the quantity applies only to the part of the grid box of the named type.[CF-Standard Name where cell method]; unit: m

liquid_water_content_of_snow_layer-where_sea_ice [CF-Standard Name-where cell method]; unit: m

Relative vorticity is the upward component of the vorticity vector i.e. the component which arises from horizontal velocity. [CF-Standard Name]; unit: s-1

surface_temperature where land or land ice [CF-Standard Name-where cell method]; unit: K

The surface called "surface" means the lower boundary of the atmosphere.[CF-Standard Name]; unit: Pa
