Do you have a database or maps for SO2 emissions in all the world?
We don't produce any datasets for global SO2 emissions, but there are
several places where you can find such data.
One place is the Canadian Global Emissions Interpretation Centre, and you can
see some of the inventories available at: http://www.ortech.ca/cgeic/
Another dataset is the NOx and SO2 Emission Data Bases for Atmospheric
Chemistry Studies from the Lawrence Livermore National Laboratory (LLNL),
available at: http://gcmd.nasa.gov/records/GCMD_LLNL_TRACE_GAS.html
Another dataset is the EDGAR system of the Netherlands Environmental
Assessment Agency, at: http://www.mnp.nl/edgar/model/edgarv32/acidifying/Sulfur_Dioxide.jsp
There are probably many more, but these are a few examples.
