“…The low standard deviations, represented by a blue and gray shaded areas, provide information on the low inter-annual variability in the shape of the maximum depleted ozone profile, as other previous studies have pointed out. These data reassert the low inter-annual variability of the Antarctic ozone loss (Kuttippurath et al, 2010). The general evolution of ozone loss inside of the polar vortex exhibits a phase of a slow ozone decline, followed by a period of quick ozone destruction.…”

“…Assuming a linear relationship between ozone loss rate and EESC, Hassler et al (2011) found that a reduction of the ozone loss rate at South Pole station (SPS hereafter) will be detectable in 2017-2021 period. In recent years, estimates of the ozone loss rate based on different satellite instrumentation (Tilmes et al, 2006;Sonkaew et al, 2013), ground-based instrumentation (Kuttippurath et al, 2010(Kuttippurath et al, , 2013 and balloon-borne measurements (Hassler et al, 2011;Hoffmann et al, 2009) for the Antarctic region have been published.…”

“…The general evolution of ozone loss inside of the polar vortex exhibits a phase of a slow ozone decline, followed by a period of quick ozone destruction. The timing of each phase for a specific station depends on the geographic position with respect to the polar vortex (Kuttippurath et al, 2010). The time window of our study is focused on the period when the ozone decrease is nearly linear in time, and has been determined for each of the layers by the mean ozone evolution for the 1999-2011 data set.…”

Abstract. Thirteen years of ozone soundings at the Antarctic Belgrano II station (78 • S, 34.6 • W) have been analysed to establish a climatology of stratospheric ozone and temperature over the area. The station is inside the polar vortex during the period of development of chemical ozone depletion. Weekly periodic profiles provide a suitable database for seasonal characterization of the evolution of stratospheric ozone, especially valuable during wintertime, when satellites and ground-based instruments based on solar radiation are not available. The work is focused on ozone loss rate variability (August-October) and its recovery (NovemberDecember) at different layers identified according to the severity of ozone loss. The time window selected for the calculations covers the phase of a quasi-linear ozone reduction, around day 220 (mid-August) to day 273 (end of September). Decrease of the total ozone column over Belgrano during spring is highly dependent on the meteorological conditions. Largest depletions (up to 59 %) are reached in coldest years, while warm winters exhibit significantly lower ozone loss (20 %). It has been found that about 11 % of the total O 3 loss, in the layer where maximum depletion occurs, takes place before sunlight has arrived, as a result of transport to Belgrano of air from a somewhat lower latitude, near the edge of the polar vortex, providing evidence of mixing inside the vortex. Spatial homogeneity of the vortex has been examined by comparing Belgrano results with those previously obtained for South Pole station (SPS) for the same altitude range and for 9 yr of overlapping data. Results show more than 25 % higher ozone loss rate at SPS than at Belgrano. The behaviour can be explained taking into account (i) the transport to both stations of air from a somewhat lower latitude, near the edge of the polar vortex, where sunlight reappears sooner, resulting in earlier depletion of ozone, and (ii) the accumulated hours of sunlight, which become much greater at the South Pole after the spring equinox. According to the variability of the ozone hole recovery, a clear connection between the timing of the breakup of the vortex and the monthly ozone content was found. Minimum ozone concentration of 57 DU in the 12-24 km layer remained in November, when the vortex is more persistent, while in years when the final stratospheric warming took place "very early", mean integrated ozone rose by up to 160-180 DU.

“…According to Kuttippurath et al (2010), the edge of the vortex varies between −30 and −45 potential vorticity units (PVUs) at 475 K during the August-November period. Figure 4 shows the −30 and −45 PVU boundaries of the vortex at 475 K, using the ECMWF operational analysed potential vorticity (PV) field for several example comparisons.…”

Validation of ozone profiles measured from a nadir looking satellite instrument over Antarctica is a challenging task due to differences in their vertical sensitivity with ozonesonde measurements. In this paper, ozone observations provided by the Infrared Atmospheric Sounding Interferometer (IASI) instrument onboard the polar-orbiting satellite MetOp are compared with ozone profiles collected between August and October 2010 at McMurdo Station, Antarctica, during the Concordiasi measurement campaign. The main objective of the campaign was the satellite data validation. With this aim 20 zero-pressure sounding balloons carrying ozonesondes were launched during this period when the MetOp satellite was passing above McMurdo. This makes the dataset relevant for comparison, especially because the balloons covered the entire altitude range of IASI profiles. The validation methodology and the collocation criteria vary according to the availability of global positioning system auxiliary data with each electro-chemical cell ozonesonde observation. The relative mean difference is shown to depend on the vertical range investigated. The analysis shows a good agreement in the troposphere (below 10 km) and middle stratosphere (25–40 km), where the differences are lower than 10%. However a significant positive bias of about 10–26% is estimated in the lower stratosphere at 10–25 km, depending on altitude. The positive bias in the 10–25 km range is consistent with previously reported studies comparing in situ data with thermal infrared satellite measurements. This study allows for a better characterization of IASI-retrieved ozone over the polar region during ozone depletion/recovery processes
