Atmospheric carbon monoxide - Latitudinal distribution of sourcesGlobal measurements of CO, taken over 2-8 years at 16 sites, are used to estimate the latitudinal and seasonal distributions of the sources. It is found that the most concentrated sources of CO, amounting to some 30 percent of the global production, are in the industrialized regions bounded by 30 and 50 deg N. About 47 percent of CO comes from the whole of the midnorthern latitudes and another 40 percent comes from the tropics. The calculations show that the production of CO is significantly higher during spring and summer, particularly in the industrialized latitudes. From these results it is apparent that the observed seasonal cycle of CO concentrations cannot be explained by the seasonal variation of OH alone.
