Decreasing Global Visibility Linked to Increasing Particulate Matter

From Science Daily (March 13th, 2009) "Air Pollution: Clear Sky Visibility Over Land Has Decreased Globally, Indicative Of Increased Particulate Matter"

A University of Maryland-led team has compiled the first decades-long database of aerosol measurements over land, making possible new research into how air pollution changes affect climate change.

According to the researchers, the visibility data were compared to available satellite data (2000-2007), and found to be comparable as an indicator of aerosol concentration in the air. Thus, they conclude, the visibility data provide a valid source from which scientists can study correlations between air pollution and climate change.
