title: Atmospheric aerosols: increased concentrations during the last decade.
abstract: Atmospheric turbidity values calculated each month from solar radiation observations at MaunaLoa Observatory, Hawaii, show an increase of aerosols from 1958 through the present. These data indicate that either the effects of the Mount Agung eruption are still being observed or a longer-term trend of increasing turbidity is in evidence.
