Ultraviolet radiation and aerosol monitoring at Lampedusa, Italy
Main Article Content
Abstract
The measurements of UV spectral irradiance, ozone and aerosol load obtained with a double monochromator Brewer
at the Station for Climate Observations of the National Agency for New Technology, Energy and Environment
(ENEA) in Lampedusa, Italy, are presented. To derive the aerosol optical depth, the direct-sun measurements at
the Brewer operational wavelengths (302.1, 306.3, 310.1, 313.5, 316.8 and 320.1 nm) were calibrated using the
Langley method. A radiative transfer model was used to investigate the role of ozone and aerosols in modulating
UV irradiance and to reproduce the measured UV spectra. The optical scattering and absorption properties of
aerosols input to the model have been derived from measured size-distributions. The modelled and measured UV
spectra are in agreement for different atmospheric conditions and allowed us to estimate the radiative impact of
the aerosols for two case studies related to the PAUR II campaign held in 1999.
