The sunburn effective UV radiation is the biologically weighted radiation being responsible for the sunburn. It results from an integration of the the wavelength-dependent physical UV irradiance at ground level weighted by the biological sensitivity of the skin getting sunburnt ...

The UV Index is an internationally standardized measure of the sunburning effect of UV radiation. It is derived as an integer value from the measured sunburn effective UV irradiance on a horizontal surface ...

The sunburn-effective UV dose is the total amount of sunburn-active UV radiation added up over the day ...

The total solar radiation is the entire radiant power of the sun which strikes a horizontally oriented surface. The total radiation includes the areas UV radiation, visible light and infrared heat radiation ...

The solar insolation is the total radiated power of the sun (total solar radiation) summed up over the day ...
