Aerosol climatology from ground-based measurements for the southern North Sea

Compared to the standard aerosol models differences in the Ångström wavelength exponent α440−870 , the single scattering albedo and the refractive index are detected. Based on these observations a new aerosol model for the atmospheric correction of coastal water reflectance spectra of the imaging spectrometer MERIS/ENVISAT was set up, which meets in particular the higher Ångström wavelength exponent of the coastal sites compared to standard maritime conditions.
