Resumen : | This work presents a comparison of aerosol properties measured by in situ and remotesensing
instrumentation over an urban background site in Madrid (Spain) in autumn
2010. Aerosol size distribution was characterized at ground level by the combined use
of two instruments and also in elevated layers by airborne in situ instrumentation.
Simultaneously, vertically resolved lidar profiles provided information about the optical
properties of aerosols present in the different layers observed. Backscatter-derived
Ångström exponent, calculated using Mie theory with volume size distribution
detected experimentally, yielded values lower than 0.5 near ground level, increasing
to over 1.5 in elevated layers. The same trend was observed for values obtained using
the lidar system. Size distribution measured at elevated layers indicated that the large
exponents observed there are associated with size distribution, with a negligible
contribution of coarse particles. The results are compromised by the major uncertainty
associated with the backscatter-derived Ångström exponents, due to the low aerosol
load detected in the elevated layers. |
