CONTAMINATION OF ARCTIC AIR AT 3 SITES DURING A HAZE EVENT IN LATE WINTER 1986

Interpretation of simultaneous measurements at three stations in diffe rent parts of the Arctic suggests that during winter air masses are fo rced into the Arctic from Eurasia in a surge towards Alaska and furthe r return over the North Pole towards the European Arctic. On some occa sions direct flow of the Eurasian air masses was detected in the Europ ean Arctic. Simple statistical methods and dispersion modelling proved useful in studying source-receptor relationships in the Arctic.
