Abstract : Measurements were made at two AFGL-operated measurement sites in the vicinity of Cape Cod: the AFGL Weather Test Facility at Otis AFB and a remote coastal site at the Nobska Lighthouse, Woods Hole. Precursor aerosol measurements including particle and CCN concentrations, aerosol mass loading, chemical composition, and ambient visibility were obtained on a daily basis for correlation with the visibility measured in subsequent fogs or hazes associated with increasing ambient humidity. Additionally, the differences between the aerosol characteristics measured at the coastal and inland sites were investigated, and the utility of using the general wind field pattern to infer air mass aerosol characteristics was assessed.
