Measurements of ultraviolet erythemal radiation (UVER)made during twoyears at three sites located at altitudes over 1000ma.s.l. in Northwestern Argentina (Salta, San Carlos, and El Rosal) have been used to estimate and analyzethe UV Index (UVI) and the cumulative doses at these locations. For the UVER irradiance, data of January (maximumvalues) and June (minimumvalues) have been analyzed as representative of the year for all locations. The UVI reaches extreme (N11) values in N20% of the analyzed days in Salta (1190 m a.s.l.), while these are reached in San Carlos (1611ma.s.l.) and El Rosal (3355ma.s.l.) in N40% of the analyzed days. Finally, the cumulative doses over an average year have also been studied for each location. The doses received during austral summer and autumn are of the same order, and represent one third of the annual dose, while the doses received during austral winter and spring represent one sixth of the annual dose approximately.
