Hannover's air quality reflects its position in the North German plain, with vehicle traffic on the A2 and surrounding Autobahn network the primary local emission source in this major trade fair and industrial city. The flat Lower Saxony terrain provides reasonable wind dispersal on most days, while winter residential wood burning and industrial emissions from the surrounding Hanover region contribute seasonal PM2.5 variation.
