Physical and optical aerosol properties at the Dutch North Sea coast

Physical and optical aerosol properties at the Dutch North Sea coast based on AERONET observations

Sun photometer measurements at the AERONET station at the North Sea coast in The Hague (The Netherlands) provide a climatology of optical and physical aerosol properties for the area. Results are presented from the period January 2002 to July 2003. For the analysis and interpretation these data are coupled to chemical aerosol data from a nearby station of the Dutch National Air Quality Network....
