“…Two quartz-based telescope assemblies and an equatorial set-up allow sun tracking for direct solar radiation measurements [4]. The DOAS instruments were calibrated with a Brewer spectrophotometer in Punta Arenas, Chile, and Dobson spectrophotometer no 13 in Lisbon, Portugal, showing a difference of no more than 3% when estimating total ozone column at mid-day [5]. Ground-based total ozone data shown in this work were taken at around noon solar time at the reported ground stations on clear sky days.…”

The evolution of the total ozone measured by a network of ground stations located in Argentina and Chile between latitudes 53S and 33S during the spring of 1993, 1994 and 1995 is given. Ozone data obtained from the ground stations are compared with total ozone values supplied by the satellite showing a very good agreement. Ground station data were taken with a very low cost detection system based on differential optical absorption techniques under specific conditions. Several ozone depletion events were detected in the south of Argentina and Chile during those time intervals, even at latitudes as low as 33S. Potential vorticity maps obtained for those events indicate that the ozone depletions observed have an Antarctic origin.

“…Definido como la porción del espectro electromagnético entre 100 y 400 (nm) nanómetros (nm), está formada por tres subtipos distintos ('A','B', y 'C') en función de la banda del espectro que ocupan. En el rango de 280nm a 315nm la radiación UV-B es más peligrosa que los rayos UVA, siendo implicado como la causa principal de cáncer de piel, quemaduras solares y cataratas oculares [1]. El deterioro progresivo que ha sufrido la capa de ozono en las últimas dos décadas [2,3,4], puede tener consecuencias importantes en los seres vivos en la tierra, ante un incremento eventual de la radiación solar ultravioleta B (UVB: 280-320 nm atenuada por la capa de ozono [3].…”

Resumen. Se denomina radiación solar a los conjuntos de radiaciones electromagnéticas emitidas por el sol. Esta energía juega un papel determinante en diversos procesos en la biosfera, su sobre exposición genera impactos sobre la salud de personas, animales y plantas. El presente artículo desarrolla un análisis sobre el comportamiento estacional de la Radiación Ultravioleta en diferentes sectores de la Región Piura. Costa Norte del Perú. La metodología aplicada considera la información procedente del sensor IUV biometer modelo 501-A (Solar Light), SN 10734 (respuesta espectral 250/380 nm), periodo 2008-2011. Desde un aspecto cualitativo, hemos empleado la escala de valores del Índice UV, definida de 1 a 14+ según la Meteorological World Organization incluidas las recomendaciones efectuadas por instituciones dermatológicas. Los resultados, demuestran la variabilidad del índice de radiación ultravioleta en función de la estacionalidad, a su vez que Piura presenta niveles de radiación ultravioleta entre altos a extremos durante todo el año lo cual representa una alerta a fin de informar a la población sobre las formas de cómo evitar los problemas e impactos en la piel.Palabras clave.

Solar radiation to the electromagnetic was emitted by the sun. This energy plays an important role in various processes in the biosphere, its over exposure generates impacts on the health of people, animals and plants. This article develops an analysis of the seasonal behavior of the UV radiation in different sectors of the Piura Region. Coast North of Peru. The methodology was applied to use information from the sensor UVI biometer model 501-A (Solar Light)

Abstract. During 1996, 1997, and 1998, several total ozone depletion events were detected over Madrid (40øN, 3øW) in late spring and in winter. A broadband interferential filter instrument (UV-300) centered at 298 nm was used to monitor the solar UV-B irradiance on the ground, registering UV-B levels as high as 17.1 /xW/cm 2 (May 2, 1997, solar zenith angle SZA -35 ø, 03 = 268 Dobson units). The data obtained have been compared to that measured with two commercial biometers (PMA2102 and Solar Light 501A), showing that the evolution of UV-B due to total ozone changes are better followed with broadband instruments with effective windows centered at lower wavelength than with instruments responding to the erythemal action spectra. The development of simple, portable, and reliable instruments for the analysis of solar UV-B phenomena at the highenergy side of that band is advocated. IntroductionThe analysis of the historical total ozone content record has revealed an ozone depletion over large geographical areas taking place over at least the last decade
