Abstract
ESTIO2005 (Experimental Study of the aTmospheric aerosol In urban envirOnment), is a field campaign for the characterization of the atmospheric aerosol from a multidisciplinary point of view. It has been developed at the Andalusian Center for Environmental Studies (CEAMA), located in South-eastern Spain in the urban area of Granada, a non-industrialized medium size city (37.16ºN, 3.58ºW and 680 m a.m.s.l.). Ground based active and passive remote sensing techniques have been combined with in situ observations in the surface boundary layer.
A Raman Lidar system based on a Nd:YAG laser source operating at 1064, 532 y 355 nm and including elastic, polarized and Raman shifted detection has been used to derive profiles of several atmospheric aerosol properties. Column integrated properties of the atmospheric aerosol has been derived by a CIMEL CE-318 radiometer. The University of Vienna Telephotometer has measured the average of the horizontal aerosol extinction coefficient between the instrument and the target at wavelengths in the range 366-700 nm.
In situ characterization of the atmospheric aerosol has been accomplished by an integrating nephelometer, TSI-3563, that operates at 450, 550 and 700 nm with possibility to determine the backscattering coefficient. Aerosol absorption coefficient at 670 nm has been determined by means of a Multi Angle Absorption Photometer (MAAP). An Aerosol Particle Sizer APS-322 (TSI) has been used to determine the aerosol size distribution in the diameter range 0.50-20 μm. Sampling of PM10 and PM2.5 were simultaneously performed, to determine major and trace aerosol components.
Temporal evolution of the different aerosol properties are presented and interpreted using additional information on synoptic situations.
