Pronto ampliaremos con notas sobre prevención de los efectos de la radiación UV sobre la salud humana.
- UV Index is a unit of measure of UV levels relevant to the effects on human skin. It serves as a vehicle to raise public awareness about the potential detrimental effects on health from solar UV exposure and to alert people of the need to adopt protective measures. The UV index is defined as erythemally (CIE) weighted irradiance, expressed in the units W/m², and multiplied by 40.
- "298.507 - 303.03nm Integrated Spectral Irradiance" is the integral of measurements taken over this wavelength region. Units are microwatts cm². Of the measures presented, this is the most sensitive to changes in total column ozone (in addition to solar angle).
- "UV-B (290-320nm Irradiance)" is the integral of spectral irradiance measurements covering the region sometimes called "UV-B". In these plots UV-B levels are influenced by cloud cover, solar angle, albedo and total column ozone. Units are microwatts cm².
- "Setlow's DNA Dose Weighted Irradiance" is the convolution of the measured spectral irradiance with a spectral weighting function determined to express the potential of UV irradiance to cause damage to DNA. From R. B. Setlow in "The wavelengths in sunlight effective in producing skin cancer: a theoretical analysis", Proc. Nat. Acad. Sci., USA, Vol. 71, no. 9, pp. 3363-3366, 1974. These data are generally most affected by solar angle and atmospheric ozone. Units are microwatts cm².
- "400-600nm Integrated Spectral Irradiance" is the spectral integral over that range. These data are generally most affected by solar angle, cloud cover, and albedo. Units are microwatts cm².
