The authors present results from measurements of negative ion densities between 24 and 30 km altitude above northern Sweden on 18 January 1992. Based on these measurements the authors infer the density of sulfuric acid vapor present, and argue that this density is too large to be explained by the source density of OH resulting from photochemical driven reactions. They offer an alternate source for hydroxyl radicals to explain their sulfuric acid measurements.
