Haze from Po Valley to Apulia Coast, Italy45.4N 9.1E
Haze hangs over the Po Valley of northern Italy, hemmed in between the Alps to the north and the Apennines to the southeast. It also spreads southeastward past the Po Delta, and then frames Italy’s Adriatic Coast, reaching southward to the shoreline of the Apulia Region.
The source of the haze could be fires, fog, or smog and air pollution. Air pollution is one important factor in climate change in Italy. Air pollutants arise from biomass burning, urban-industrial and natural sources. Under certain atmospheric circulation configurations, long-range or trans-boundary transport of pollutants, including aerosols, carbon monoxide, ozone, desert dust, mould spores and pesticide may occur over large distances and over time scales of typically four to six days (click here for more information).
