Emissions of nitrogen oxides and ammonia in 1995 at 50km resolution (tonnes of N per year)
Notes: Includes emissions from shipping in the North Sea and the north-east Altantic (Lloyd's Register of Shipping : Marine Exhaust Emission Research Programme
London, UK). Little data available for emissions from shipping in the Baltic, hardly any for the Mediterranean and the Black Sea. Emissions in these seas are largely underestimated.
