Sources and sinks of carbonyl sulfide inferred from tower and mobile atmospheric observations in the Netherlands

Carbonyl sulfide (COS) is a promising tracer for the estimation of terrestrial ecosystem gross primary production (GPP). However, understanding its non-GPP-related sources and sinks, e.g., anthropogenic sources and soil sources and sinks, is also critical to the success of the approach. Here we infer the regional sources and sinks of COS using continuous in situ mole fraction profile measurements of COS along the 60m tall Lutjewad tower (1ma.s.l.; 53 degrees 24' N, 6 degrees 21' E) in the Netherlands. To identify potential sources that caused the observed enhancements of COS mole fractions at... Mehr ...
