AB: An updated time-averaged inventory of subaerial volcanic sulfur emissions to the atmosphere is presented. This work builds upon an inventory previously compiled by Andres and Kasgnoc (1998, JGR 103:25,251-25,261), which covered a time period from the early 1970s to the mid 1990s. The updated inventory extends to the end of 2002. Data contained within the inventory consist primarily of sulfur dioxide measurements taken at volcanoes, listed as a time-averaged flux in Mg/d. This inventory may provide input to global sulfur and sulfate models, inventories of other volcanic species compiled by the species:sulfur ratio, and volcano-atmosphere interaction models. This work also contributes to the Global Emissions Inventory Activity (GEIA), whose goal is to create, maintain, and distribute reliable inventories of species important for understanding global atmospheric chemistry at a one-degree global scale.
