Greetings Volcano Listserv colleagues,

For the past three years I've been leading a working group on wildfires and
urban smoke in the Pacific Northwest. We've held around 100 webinars on all
aspects of these topics, including a few that overlapped with volcanology
(you can find a YouTube playlist with links to recordings of all the talks
at https://urldefense.com/v3/__https://www.youtube.com/playlist?list=PLQvQiqeQdTK68OFN6706xECEbxwTpYUpR__;!!IKRxdwAv5BmarQ!ZI1jTJEbocf8GtZworyEAC6MpT0WHra4Yt_kkR8WXOQu7W-oWWc32la21gdwXJtmVauTjy1aB4XzX5lc$

).

This Wednesday at 10 am Pacific time, we are having a webinar that may be
of interest to some of you, about the atmospheric impacts of massive
wildfires, like Australia's 2019-2020 "Black Summer," and major volcanic
eruptions. Dr. Peter Bernath from University of Waterloo and Old Dominion
University will discuss results from the Atmospheric Chemistry Experiment
(ACE) satellite, published in *Science* in March (
https://urldefense.com/v3/__https://www.science.org/doi/full/10.1126/science.abm5611__;!!IKRxdwAv5BmarQ!ZI1jTJEbocf8GtZworyEAC6MpT0WHra4Yt_kkR8WXOQu7W-oWWc32la21gdwXJtmVauTjy1aB3km9aES$ ), "Wildfire smoke
destroys stratospheric ozone." Besides describing the implications for a
wildfire audience, Peter is particularly interested in talking about these
results with volcano scientists.

Please join us, Wednesday June 29, at 10 am Pacific, at this Webex link:

Here's Peter's abstract:

Atmospheric Chemistry Experiment (ACE): Overview, Fire Chemistry and
Volcanic Plumes

And Department of Chemistry, University of Waterloo, Waterloo, ON.

The ACE satellite (https://urldefense.com/v3/__http://www.ace.uwaterloo.ca/__;!!IKRxdwAv5BmarQ!ZI1jTJEbocf8GtZworyEAC6MpT0WHra4Yt_kkR8WXOQu7W-oWWc32la21gdwXJtmVauTjy1aB3ZBJzVX$

[1] is measuring atmospheric
composition by solar occultation from low Earth orbit. The primary ACE
instrument
is an infrared Fourier transform spectrometer (ACE-FTS). ACE-FTS measures
infrared spectra of aerosols and clouds by removing gas phase features to
leave
â??residualâ?? spectra. So far ACE-FTS has observed spectra of Polar Mesospheric
Clouds (PMCs), Polar Stratospheric Clouds (PSCs), stratospheric smoke,
sulfate
aerosols, cirrus clouds and volcanic ash. This presentation will focus on
stratospheric
smoke particles from large wildfires and the characterization of sulfate
aerosols from
volcanic eruptions. We have discovered a new chemistry catalyzed by smoke
particles
injected into the stratosphere by extreme wildfires (â??Wildfire fire smoke
destroys
stratospheric ozoneâ?? [2]).
