subject: 2004GL021732 Request to Review from Geophysical Research Letters
Dear Dr. Briffa:
Would you be willing and available to review "Statistical distributions of ice core sulfate from climatically
relevant volcanic eruptions" by Philippe Naveau, Caspar Ammann, submitted for possible publication in the Geophysical Research Letters.
The manuscript's abstract is:
Quantitative knowledge of external climate forcing is required for
accurately attributing past climatic changes. Information on
volcanic activity over the past millennium has primarily been drawn
from high-latitude ice cores. A few large events with distinct
signatures in the ice are well known and they are commonly used as
marker events to synchronize time scales in individual ice cores.
In the past decade different efforts have been undertaken to
systematically identify lesser known eruptions and to develop
time series of past volcanic forcing. Here we mathematically quantify
the distribution of the magnitude of volcanic events that have a
climatic relevance during the past millennium.
Volcanic sulfate magnitudes of such events clearly exhibit a
``heavy tailed" extreme value distribution. Indeed, the climatically relevant
eruptions are only the extremes of global volcanic activity.
This characterization of volcanic amplitude is a fundamental step in
detection and attribution studies of past natural forcing and
of its effects on climate.
