| dc.description.abstract | During the summer of 2004 a field campaign was carried out at the El Arenosillo Atmospheric Sounding Station (ESAt), near Huelva, South-Western Spain. The campaign was designed to obtain experimental data on aerosol in situ absorption, size distribution, chemical composition, and columnar optical properties but this paper deals only with the evaluation of the absorbent aerosol. A Dekati cascade impactor and a PM10 Graseby-Andersen high volume sampler were used to collect aerosol fractions over filters. In this paper an estimation is made for the concentration of black carbon at ground level, using the absorption coefficients obtained from a filter transmission method. The values obtained are highly variable and range from 31 ng m-3 to 770 ng m-3. The high volume sampler filters were analyzed for elemental carbon with a thermal- optical method (LECO). The black carbon concentration is also compared with the columnar level retrieved from aerosol absorption optical depth derived from inversion of a sun-photometer data inside the AERONET framework. | pt_PT |
| dc.description.abstract | Durante el verano de 2004 se realizó una campaña de medida de aerosoles en la Estación de Sondeos Atmosféricos de El Arenosillo (ESAt), cerca de Huelva, sudoeste de España. La campaña estuvo destinada a la obtención de datos in situ de absorción, distribución de tamaños, composición química y propiedades ópticas de columna de los aerosoles pero el presente trabajo está dedicado solamente al estudio de los aerosoles de tipo absorbente. Se utilizaron para recoger las partículas de diferentes fracciones en filtros, un impactador de cascada Dekati y un impactador de alto volumen Graseby-Andersen PM10. En este trabajo se presenta una estimación de la concentración de black carbon a nivel de suelo, partiendo de los valores de los coeficientes de absorción obtenidos con un método basado en la transmisión de la luz por filtros con aerosoles depositados. Los valores obtenidos, altamente variables, están en el rango 31 ng m-3 -770 ng m-3 . Los filtros del impactador de alto volumen se han analizado con un método termo-óptico (LECO) para la obtención de la fracción de carbono elemental. Para terminar, la concentración de black carbon se comparó con los niveles columnares obtenidos a partir del espesor óptico de absorción de aerosoles derivado de la inversión de los datos de un fotometro solar de la red AERONET. | |
