    Notes: Abstract Surface NO and NO2 mixing ratios were measured aboard the research vessel Polarstern during the mission ANT VII/1 from 24 September to 5 October 1988. The measurements were taken along the meridian at 30° W in the Atlantic region covering latitudes between 30° N and 30° S. The average mixing ratios were about 12 pptv NO/30 pptv NO2 in the Northern Hemisphere and about 7 pptv NO/22 pptv NO2 in the Southern. Elevated mixing ratios of 20 pptv NO/70 pptv NO2 were found at 12° N (probably due to air masses originating from the surface of West Africa) and in the region of the ITCZ between 8° N and 5° N. Because of probable contamination by the ship, the measured mixing ratios mostly represent upper limits.
