The Sahara as a possible sink for trace gases

· Geophys. Res. Lett.; (United States)
Measurements of N/sub 2/O, CCl/sub 4/, CH/sub 3/Cl/sub 3/, CF/sub 2/Cl/sub 2/, and CFCl/sub 3/ concentrations in dusty and nondusty air over East Africa, the Mediterranean Sea, and the Atlantic Ocean are found to be consistent with the hypothesis that desert regions may be acting as sinks for a number of atmospheric trace gases. Dusty air has significantly lower concentrations of N/sub 2/O, CCl/sub 4/, and CH/sub 3/CCl/sub 3/, while concentrations of CF/sub 2/Cl/sub 2/ and CFCl/sub 3/ do not differ significantly for dusty and nondusty air. While these observations are in accord with the results of laboratory studies, the data are insufficient to confirm the hypothesis.
