Caracterización y comportamiento del ozono superficial en la provincia de Huelva

Abstract

_____________________________________________The development of antropogenic activities have increased ozone levels in the low troposphere. The province of Huelva presents a special characteristics to formation and accumulation of ozone surface, and therefore it was decided to start a study in year 2000, to know the levels and behaviour surface ozone. The network to measure ozone concentrations consists of four stations. To make a correct interpretation of ozone concentrations, it was necessary to know atmospheric dynamic, hence we have studied the main meteorological parameters. From the winds regime and after applying a criteria to extract breeze days of wind data, we have been able to study breeze regime. Sea-land breeze in Huelva does not present always the same behaviour and it depends on synoptic conditions. We have made a study to know seasonal and daily variability surface ozone in this region. The relation between ozone concentrations and several meteorological variables such as temperature, wind speed and relative humidity, and other atmospheric parameters has been analysed. We have also evaluated the number of exceedances of the different thresholds such as health protection and vegetation protection. We have studied the behaviour surface ozone under different atmospheric conditions, thus under advection situations the ozone concentrations show small cycles while under typical sea-land breezes take place the episodes of air pollution by ozone.

El desarrollo de las actividades antropogénicas ha llevado al incremento de las concentraciones de ozono en la baja troposfera. La provincia de Huelva presenta una serie de condiciones ideales para la formación y acumulación de ozono, por ello se decide en el año 2000 realizar un estudio sobre los niveles y el comportamiento que muestra este gas. Las medidas de ozono se han realizado en cuatro puntos de la provincia. Para realizar una correcta interpretación de las medidas fue necesario estudiar la dinámica de la baja atmósfera, estudiándose los principales parámetros meteorológicos. A partir de los datos de viento se extrajeron los días con brisa costera y se pudo conocer que el comportamiento de la brisa depende de las condiciones sinópticas. La relación entre el ozono y varios parámetros meteorológicos han sido analizados. Se ha evaluado el número de superaciones de los umbrales de protección de la vegetación y de la salud humana. Se ha estudiado el comportamiento del ozono bajo diferentes escenarios meteorológicos, con concentraciones bajas de ozono bajo situaciones advectivas y episodios de ozono con condiciones de brisa costera.
