Abstract:
The Global Emissions Inventory Activity (GEIA) is an activity of the International Global Atmospheric Chemistry (IGAC) Core Project of the International Geosphere-Biosphere Program (IGBP). The focus of GEIA is to make global emissions available on a one degree grid.
A time-averaged inventory of subaerial volcanic sulfur emissions is presented primarily for the use of global sulfur and sulfate modelers. This inventory is based upon the 25 year history of making sulfur, primarily sulfur dioxide, measurements at volcanoes. These "hard" data are then extrapolated to other volcanoes. Actual measurements of subaerial volcanic SO2 emissions indicate a time-averaged flux of 13 Tg/a SO2 based upon an early 1970's to 1997 time frame. When considering the other sulfur species also present in volcanic emissions, a time-averaged inventory of subaerial volcanic sulfur emissions is 10 Tg/a S.
The GEIA repository for this inventory contains nine files. The file, volcanos.txt, is a copy of the inventory description. Volcano altitudes are in volcalt.txt and the references used to construct the inventory in bibliography.txt. Volcano locations are stored in LOCavg1.1a and plotted in LOCavg1.ps. SO2 from continuously emitting volcanoes are stored in COVavg1.1a and plotted in COVavg1.ps. SO2 from sporadically emitting volcanoes are stored in SPVmax1.1a and plotted in SPVmax1.ps.
