erythemal irradiance [Eer]

effective irradiance with the spectral irradiance, Eλ, spectrally weighted with the erythema spectral weighting function, ser(λ), normalized to 1 at its maximum

Unit: W⋅m-2

NOTE This definition implies that an action spectrum is adopted for the actinic effect considered, and that its maximum value is 1. When giving a quantitative amount, it is essential to specify according to which actinic action spectrum the irradiance is meant, as the unit is the same.
