Determining nonmethane hydrocarbon

Authors


Abstract

In May 1987, an intercomparison exercise for the determination of nonmethane hydrocarbon gases in the marine atmosphere was conducted. A preliminary account of the results was presented at the 1987 AGU Fall Meeting (see the abstract “Non-Methane Hydrocarbons in the Remote Marine Atmsophere: Results of an Intercomparison Exercise,” in Eos, November 3, 1987, p. 1220).

It has subsequently become evident that miscalculations occurred (in the conversion of units) that resulted in incorrect mixing ratios for some data sets as presented. A corrected report is in progress and will be published as soon as possible.
