AERday cod day longitude latitude time atmosphere_optical_thickness_due_to_cloud Cloud Optical Depth The optical thickness is the integral along the path of radiation of a volume scattering/absorption/attenuation coefficient. The radiative flux is reduced by a factor exp(-optical_thickness) on traversing the path. A coordinate variable of radiation_wavelength or radiation_frequency can be specified to indicate that the optical thickness applies at specific wavelengths or frequencies. The atmosphere optical thickness applies to radiation passing through the entire atmosphere. 'Cloud' means the component of extinction owing to the presence of liquid or ice water particles.

AERmon cod mon longitude latitude time atmosphere_optical_thickness_due_to_cloud Cloud Optical Depth The optical thickness is the integral along the path of radiation of a volume scattering/absorption/attenuation coefficient. The radiative flux is reduced by a factor exp(-optical_thickness) on traversing the path. A coordinate variable of radiation_wavelength or radiation_frequency can be specified to indicate that the optical thickness applies at specific wavelengths or frequencies. The atmosphere optical thickness applies to radiation passing through the entire atmosphere. 'Cloud' means the component of extinction owing to the presence of liquid or ice water particles.

CFsubhr rsus subhrPt site time1 surface_upwelling_shortwave_flux_in_air Surface Upwelling Shortwave Radiation The surface called 'surface' means the lower boundary of the atmosphere. 'shortwave' means shortwave radiation. Upwelling radiation is radiation from below. It does not mean 'net upward'. When thought of as being incident on a surface, a radiative flux is sometimes called 'irradiance'. In addition, it is identical with the quantity measured by a cosine- collector light-meter and sometimes called 'vector irradiance'. In accordance with common usage in geophysical disciplines, 'flux' implies per unit area, called 'flux density' in physics. atmos W m-2 up area: point time: point

The phrase 'residual mean advection' refers to the sum of the model's resolved advective transport plus any parameterized advective transport. Parameterized advective transport includes processes such as parameterized mesoscale and submesoscale transport, as well as any other advectively parameterized transport. When the parameterized advective transport is represented in the model as a skew-diffusion rather than an advection, then the parameterized skew diffusion should be included in this diagnostic, since the convergence of skew-fluxes are identical (in the continuous formulation) to the convergence of advective fluxes. ocean W m-2 area: mean where sea time: mean area: areacello volume: volcello

The phrase 'residual mean advection' refers to the sum of the model's resolved advective transport plus any parameterized advective transport. Parameterized advective transport includes processes such as parameterized mesoscale and submesoscale transport, as well as any other advectively parameterized transport. When the parameterized advective transport is represented in the model as a skew-diffusion rather than an advection, then the parameterized skew diffusion should be included in this diagnostic, since the convergence of skew-fluxes are identical (in the continuous formulation) to the convergence of advective fluxes. ocean W m-2 area: mean where sea time: mean area: areacello volume: volcello

day zg day longitude latitude plev8 time geopotential_height Geopotential Height 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. atmos m time: mean area: areacella

fx zfull fx longitude latitude alevel height_above_reference_ellipsoid Altitude of Model Full-Levels Height of full model levels above a reference ellipsoid. A reference ellipsoid is a mathematical figure that approximates the geoid. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. The ellipsoid is an approximation because the geoid is an irregular shape. A number of reference ellipsoids are defined for use in the field of geodesy. To specify which reference ellipsoid is being used, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention. atmos m area: mean area: areacella
