Atmospheric distribution and sources of nonmethane hydrocarbonsThe paper discusses the atmospheric distribution of natural and man-made nonmethane hydrocarbons (NMHCs), the major species of airborne NMHCs, and their sources and sinks. Particular attention is given to the techniques for measuring atmospheric NMHCs; diurnal and seasonal variations of atmospheric NMHCs and differences between rural, urban, and marine environments; latitudinal and vertical distributions; and available stratospheric NMHC measurements. A formula defining the atmospheric lifetime of a NMHC from its reaction rates with OH and O3 is presented.
