Study on aerosol properties over Madrid (Spain) by multiple instrumentation during SPALI10 lidar campaign
Understanding the effect of aerosols upon radiative forcing requ
ires information about vertical profiles. Lidar techniques
represent a powerful tool for studies of the vertical structure
of the aerosol field. During the SPAin Lidar Intercomparison 20
10 (SPALI10) campaign, several multiwavelen
gth Raman lidar systems measured simultaneously in order to assess their performances. Multiwavelength lidars can pr
ovide relevant vertically-resolved information on aerosol optical
properties because the wavelength dependence of the backscatter and extinction coefficients allows for a more detailed discrimination of aerosol types. Several lidar stations belonging to SPALINET, the Spanish and Portuguese Lidar NETwork and also EARLINET, the European Aerosol Research Lidar NETwork, intercompared during a campaign that took place in Madrid from 18 October to 5 November 2010. The products provided by the lidar systems were compared with ancillary data.
At ground level, aerosol size distribution was continuously monitored. Additionally, the column-integrated characterization of the atmospheric aerosol was performed by means of a sun photometer. The extensive dataset obtained during SPALI10 field campaign enables to compare ground-level in-situ measurements with remote sensing techniques to determine vertically-resolved optical and microphysical properties of aerosols. Several relevant features shown in the comparison of the results obtained by the different instruments
are discussed in this work.Peer Reviewe

Study on aerosol properties over Madrid (Spain) by multiple instrumentation during SPALI10 lidar campaign
Cuatro sistemas lidar Raman multifrecuencia (Madrid, Granada, Barcelona y Evora), tomaron
medidas simultáneamente a un sistema de referencia (Potenza) para verificar su funcionamiento
durante la campaña de intercomparación: SPALI10, (SPAin Lidar Intercomparison 2010) que tuvo
lugar en Madrid entre el 18 de Octubre y el 5 de Noviembre de 2010. Estos sistemas lidar Raman
multifrecuencia proporcionan propiedades ópticas de los aerosoles con resolución vertical. Los
perfiles suministrados por los sistemas lidar se compararon con información complementaria
proporcionada por otra instrumentación, tal como la distribución de tamaños de los aerosoles
medida de manera continua a nivel de superficie o la caracterización de la columna de aerosole
