Taking a 2-year atmospheric record of atmospheric oxygen and the greenhouse gases N₂O, CO₂, and CH₄, made at a coastal site in the Namib Desert, we estimated the fluxes of these gases from upwelling events in the northern Benguela Current region. We compared these results with flux measurements made on a research vessel in the study area at the same time and found that the two approaches agreed well. The study region was a source of N₂O, CO₂, and CH₄ to the atmosphere during upwelling events.
