Set up a default aerosol according to Shettle (1989). The default properties are a rural type aerosol in the boundary layer, background aerosol above 2km, spring-summer conditions and a visibility of 50km. These settings may be modified with aerosol_haze, aerosol_vulcan, aerosol_season, and aerosol_visibility.
