Short summary
We comprehensively screen and process global hourly visibility data to construct a more reliable monthly inverse visibility (1/Vis) data set, and to infer trends in atmospheric haze. Consistency is found for the inferred 1/Vis seasonality and trends with other collocated in situ aerosol measurements over the US and Europe. Trends of 1/Vis over 1945–1996 for the eastern US, and over 1973–2013 for Europe and eastern Asia are significantly associated with the variation of SO2 emission.
