Dear all, I have been unable to find appropriate standard names for Direct (aka 'beam') shortwave radiation. Diffuse and Global SW radiation are listed already.
Unless I've missed something, I suggest the following additions: direct_downwelling_shortwave_flux_in_air<javascript:void(0)> (unit: W m-2) Downwelling radiation is radiation from above. It does not mean "net downward". 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. "shortwave" means shortwave radiation. "Direct" (also known as "beam") radiation is radiation that has followed a direct path from the sun and is alternatively known as "direct insolation". surface_direct_downwelling_shortwave_flux_in_air<javascript:void(0)> (unit: W m-2) Downwelling radiation is radiation from above. It does not mean "net downward". "Direct" (also known as "beam") radiation is radiation that has followed a direct path from the sun and is alternatively known as "direct insolation". 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. The surface called "surface" means the lower boundary of the atmosphere. "shortwave" means shortwave radiation.
