Sensitivity of UV erythemally effective irradiance and daily dose to spatial variability in total ozone.

摘要: The total ozone column (TOC) is the most significant quantity for estimating erythemally effective UV radiation under clear sky conditions. Uncertainties in TOC measurements and a limited spatial temporal resolution therefore influence quality of calculated radiation. Index, internationally accepted measure radiation, used public media to inform about current levels builds base sun protection. Thus, accuracy promoted values essential. While preceding study we estimated measurement uncertainties, this analyze gaps variability irradiance at noon daily dose. results allow defining necessary when certain Index or purpose protection required. In case reveals that assumption invariability causes similar uncertainties independent geographic location. At higher latitudes counteracts lower level irradiance. For dose have an even impact latitudes.
