Sunphotometer data from PML

In May 2001 a PREDE POM01-L was installed on the roof of the Plymouth Marine Laboratory to continue the atmospheric correction research of the PML Remote Sensing Group. This was to replace the AERONET CIMEL sunphotometer situated at Rame Head which was decommissioned in 1999. The instrument operates at 7 wavelengths (315, 400, 500, 670, 870, 940 and 1020nm) and scans at pre-set angles away from the solar disk to determine, using the inversion code of Nakajima et al. (2006), various properties of tiny particles called aerosols within the atmospheric column. From these measurements useful atmospheric aerosol parameters such as the Aerosol Optical Thickness (AOT), aerosol size distribution and single scattering albedo can be calculated. Marine aerosols tend to be bigger (D > 1µm) than those generated over the land (0.01 < D < 1µm) and are of a different chemical composition; marine aerosols are salt particles whereas terrestrial aerosols are sulphate compounds.
