Resumen
Objetivos: Implementar un modelo radiativo
para realizar el pronóstico de la radiación ultravioleta (RUV) eritémica
(de efecto en la piel humana) en Huancayo. Métodos: La
investigación fue descriptiva comparativa. Se utilizó el modelo
Tropospheric Ultraviolet Visible (TUV) del National Center for
Atmospheric Research (NCAR). Se acondicionaron los parámetros de ingreso
para las condiciones atmosféricas de Huancayo, como la distribución
vertical de ozono y temperatura, la climatología de ozono total, la
altura y el albedo de la ubicación. Con estos datos de ingreso el modelo
generó datos cada 3 minutos durante las 24 horas de los 365 días del
año. Para su validación se utilizaron mediciones en tierra,
sincronizándolo con el radiómetro espectral GUV-511 Biospherical Inc.,
que brinda mediciones a 305, 320, 340 y 380 nm. Se determinó el
coeficiente de correlación de Spearman para la evaluación estadística. Resultados:
El análisis determinó la buena capacidad de réplica del modelo TUV de
la variación horaria de la RUV en esta ubicación. Así también, el
análisis estadístico de los datos reportó un coeficiente de correlación
promedio de 0,88 (p<0,05) y se pudo validar el modelo, haciendo una
evaluación individual de datos en días despejados y nublados. Conclusiones:
Esto permitió implementar el modelo TUV para pronosticar la
climatología anual de la RUV eritémica en Huancayo, en términos del
Índice UV, para brindar una información cuantitativa a la población
sobre los niveles de RUV a la que están expuestos, el tiempo máximo de
exposición al sol sin riesgo y con ello tomar decisiones para proteger
su salud.
Objectives: Implement a radiative model to forecast the erythemal (that affects the human skin) UV radiation (UVR) in Huancayo city. Methods: The research was descriptive and comparative. It was used the Tropospheric Ultraviolet Visible (TUV) model of the National Center for Atmospheric Research (NCAR). It was conditioned the input parameters for atmospheric conditions of Huancayo, like: ozone and temperature vertical distributions, total ozone climatology, altitude and albedo of the location. With these input data the model generated data every 3 minutes during the 24 hours of the 365 days of a year. For model validation, it was used ground measurements. For this, it was synchronized the spectral radiometer instrument GUV-511 of Biospherical Inc. that provides measurements at 305, 320, 340 and 380 nm. It was determined the Spearman’s correlation coefficient for statistical evaluation. Results: The analysis determined the good ability of TUV model to replicate the hourly variation in this location. Thus, also, the statistical analysis of the dataset reported a mean correlation coefficient of 0.88 (p<0.05) and it was possible to validate the model, making a detailed evaluation with data of cloudy and cloud-free days. Conclusions: It was possible to implement a radiative model, TUV, for forecast the annual climatology of erythemal UV radiation at Huancayo, in terms of the UV index. It will be useful to provide quantitative information to the population about the UV radiation levels that they are exposed, the maximum time for sun exposure without risk and with it to take decisions to protect their health.
