ABSTRACT
The short wavelength cut-off (lambdac), the wavelength of the maximum spectral UV (lambdaMax) of spectral pre-vitamin D3 effective solar UV irradiance (UVD3), and the spectral erythemal UV (UVEry) were compared at 5-min intervals over a 6-month period at solar zenith angles (SZA) ranging from 4.7 degrees to 80 degrees. Averaged over the entire period, lambdac for UVD3 is higher by 1.05 nm than that for UVEry. The lambdaMax is higher for UVD3 compared to UVEry for SZA
