It is often assumed that atmospheric observations atremote sites represent long-range transport of airbornematerial, and local influences are overlooked. We evaluated the impact of local input on the rainwatercomposition at Gosan Station, a strategic sitefor monitoring the continental outflow from Asia. We analyzed a 14-year record of rainwater chemicalcomposition archived by the Korea MeteorologicalAdministration and detected local terrestrial contributionfor nitrate, sulfate and ammonium. We alsomeasured the chemical composition of rainwatersampled simultaneously at multiple locations withinthe premises of the Gosan Station, from which localinfluence with meter-scale spatial heterogeneitycould be discerned. We estimate that the local inputaccounted for at least ~10% of the wet deposition ofnitrogen and ~12% of the wet deposition of sulfurduring the 14 years. This highlights the significance ofthe local influence, which should be carefully assessedwhen interpreting atmospheric observations atthis site.
