10/29/2010 – Exploring the Antarctic Ozone Hole using Long-Duration Balloons

Speaker: Linnea Avallone (LASP/ATOC)
Date: Friday, Oct 29, 2010
Time: 4:00pm
Location: Duane, Gamow tower

Seminar Abstract:

The Antarctic “Ozone Hole” was first reported in the literature 25 years ago by Farman et al. [1985]. Despite intense research in the ensuing years into the chemical, microphysical and dynamical processes that create this phenomenon, there remain sufficient gaps in our knowledge that we cannot say with certainty when in the future the “ozone hole” will disappear. In this talk, I will discuss the recent (August-October 2010) Concordiasi campaign – a series of balloon-borne payloads designed to address some of the outstanding issues related to polar stratospheric ozone loss. I will describe the experiment design, including the unique super-pressure balloon platform and scientific instruments, and will present some preliminary data from ozone sensors still circumnavigating the Antarctic stratosphere.
