Summary
Abstract: This data set consists of volcanic and aerosol data used in the construction of
the estimated aerosol optical depth history. The first file is a list of
radiocarbon dated eruptions from which a subset of all unique events was
extracted by eliminating duplicate dates from a common location.

The second file is the observed annual hemispheric mean aerosol optical depth
(AOD), taken from Goodman (1984). This was used throughout the studies
summarized here in the conversion of the volcanicity index into a long
history of aerosol optical depth (Bryson, 1988). This 40000 year long
estimate of AOD is also given in table App 3 in:
