It does not mean \"net downward\". The term \"shortwave\" means shortwave radiation. 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. A phrase \"assuming_condition\" indicates that the named quantity is the value which would obtain if all aspects of the system were unaltered except for the assumption of the circumstances specified by the condition. \"Clean sky\" means in the absence of atmospheric aerosol. \"Clear sky\" means in the absence of clouds."@en ; skos:notation "SDN:P07::B7IXS3WH" ; skos:note "deprecated"@en ; skos:prefLabel "downwelling_shortwave_flux_in_air_assuming_clean_clear_sky"@en ; skos:related .
