Other Biological Effects - Measurements:

The following graphs provide measured biologically effective irradiance with a temporal resolution of 30 minutes.
Beside irradiance, necessary exposure times or exposure limits are provided.
Measurements and times refer to an horizontally oriented receiver with free horizon (field of view =180 degrees).
"Global" denotes measurements of the whole sky, while for "Diffuse" irradiance measurments, the sun is masked by a so-called shadow band.
