Acidity-driven gas-particle partitioning of nitrate regulates its transport to Arctic through the industrial era

Abstract Anthropogenic NOx emissions have altered the biogeochemical nitrogen cycle since the Industrial Revolution, yet Arctic ice core nitrate (NO3 −) records are inconsistent with post-1970s NOx emission reductions. Here we show a NO3 − deposition history covering 1800–2020 using an ice core from...
