| description | <p>Stratospheric ozone loss
inside the Arctic polar vortex for the winters between 2004–2005 and
2012–2013 has been quantified using measurements from the space-borne
Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS).
For the first time, an evaluation has been performed of six different ozone
loss estimation methods based on the same single observational dataset to
determine the Arctic ozone loss (mixing ratio loss profiles and the
partial-column ozone losses between 380 and 550 K). The methods used are the
tracer-tracer correlation, the artificial tracer correlation, the average
vortex profile descent, and the passive subtraction with model output from
both Lagrangian and Eulerian chemical transport models (CTMs). For the
tracer-tracer, the artificial tracer, and the average vortex profile descent
approaches, various tracers have been used that are also measured by ACE-FTS.
From these seven tracers investigated (<span class="inline-formula">CH<sub>4</sub></span>, <span class="inline-formula">N<sub>2</sub>O</span>, <span class="inline-formula">HF</span>,
<span class="inline-formula">OCS</span>, CFC-11, CFC-12, and CFC-113), we found that <span class="inline-formula">CH<sub>4</sub></span>,
<span class="inline-formula">N<sub>2</sub>O</span>, <span class="inline-formula">HF</span>, and CFC-12 are the most suitable tracers for
investigating polar stratospheric ozone depletion with ACE-FTS v3.5. The
ozone loss estimates (in terms of the mixing ratio as well as total column
ozone) are generally in good agreement between the different methods and
among the different tracers. However, using the average vortex profile
descent technique typically leads to smaller maximum losses (by approximately
15–30 DU) compared to all other methods. The passive subtraction method
using output from CTMs generally results in slightly larger losses compared
to the techniques that use ACE-FTS measurements only. The ozone loss
computed, using both measurements and models, shows the greatest loss during
the 2010–2011 Arctic winter. For that year, our results show that maximum
ozone loss (2.1–2.7 ppmv) occurred at 460 K. The estimated partial-column
ozone loss inside the polar vortex (between 380 and 550 K) using the
different methods is 66–103, 61–95, 59–96, 41–89, and 85–122 DU for
March 2005, 2007, 2008, 2010, and 2011, respectively. Ozone loss is difficult
to diagnose for the Arctic winters during 2005–2006, 2008–2009, 2011–2012,
and 2012–2013, because strong polar vortex disturbance or major sudden
stratospheric warming events significantly perturbed the polar vortex,
thereby limiting the number of measurements available for the analysis of
ozone loss.</p> |
