This parameter is of special interest in agricultural
meteorology.
- The duration of sunshine (units hr per day) allows for
estimates of the energy available for physical and bio-
logical processes
For accurate investigations, measurements of the different
radiation (solar and terrestrial) fluxes are required. In
meteorology, the following radiation fluxes are measured
- Solar radiation fluxes (shortwave length 0.29 - u)
. Direct solar radiation is measured at normal incidence.
. Global solar radiation downward direct and diffuse solar
radiation received on a horizontal surface from a solid
angle of 2 PI.
. Sky radiation downward diffuse solar radiation received on
a horizontal surface.
. Reflected global radiation Solar and diffuse radiation
reflected by the surface (bare or covered by vegetation)
