Measurement of Ambient Concentration and Surface Fluxes of O₃, SO₂ NO_x and TSP in Uludag National Park

Summary

Uludag station is situated in the northwest part of the Turkey at longitude 40° 10¹ N, and latitude 20° 08¹ E (Fig. 9.7.1). The station is operated by the Middle East Technical University and Uludag University. Based on the fact that fluctuation of ambient concentration results in the changes in the vertical fluxes, first ambient concentration data were obtained. Starting in March 1993, measurements of O₃, NO_x, SO₂ and TSP concentration at ground level have been made continuously. Meteorological parameters wind direction, wind speed, temperature and humidity were also measured continuously. Hard winter conditions at the Uludag mountain site (average snow-fall is about 1.5m) resulted in some technical problems with the instruments, which in turn resulted in some gaps in the data.
