"CFSN0108" . "CFSN0108" . "1" . . "'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." . "tropopause_upwelling_shortwave_flux"@en . "accepted" . "" . "1" .
