Experimental sampling efficiency of the glass plate method for short-lived trace gases measured in 2023@en

This data set presents sampling efficiencies for short-lived trace gases (dimethyl sulfide, isoprene, carbon disulfide) when using the glass plate method to sample the sea surface microlayer (SML). As the SML sample spreads in a thin layer on the glass plate, the loss of trace gas due to volatilization is supposedly high, but we hypothesized that sampling efficiency can be determined experimentally to correct for those losses. Interpretation of environmental trace gas measurements of the SML is difficult to not meaningful in the absence of a sampling efficiency estimate. By determining the sampling efficiency new light might be shed on the SML's role on air-sea gas exchange. […]
