The VolcanEESM database was a combination of all global volcanic emissions of SO2 (amount and location) collated from the available literature. Currently, the database is available for the period 1850-2015, but this is expected to be updated yearly with additional information.

The database includes no information about the size, mass, distribution or optical depth of resulting aerosol. As such the database is model agnostic and it is up to each modeling group to make decisions about how to implement the emission file in their prognostic stratospheric aerosol scheme.

Revisions to databases, such as VolcanEESM, are part of the scientific process. Thus, the database is freely available for others to use and report back any errors or comments they may have to the database's curators.
