Signs of the ozone recovery based on multi sensor reanalysis of total ozone for the period 1979–2017

Is the Antarctic Ozone Hole Recovering Faster than Changing the Stratospheric Halogen Loading?

“…The usefulness of satellite data for monitoring ozone long-term variability over southern high latitudes is already known (Kuttippurath et al 2018b;Krzyścin and Baranowski 2019). This can also be demonstrated by a comparison of the metric ii values (TCO3 over the South Pole) with TCO3 from ground-based observations at the Amundsen-Scott SP station (Fig.…”

“…Dynamical proxies are related to known processes affecting ozone variability such as solar activity, the poleward eddy heat flux, volcanic aerosols in the stratosphere, the quasibiennial oscillation, El Niño-Southern Oscillation, and the Antarctic Oscillation. This set of proxies has been commonly used in previous statistical models of ozone variability (e.g., Pazmiño et al 2018;Krzyścin and Baranowski 2019). The time series of the dynamical proxies were taken from the same web sites used in our previous paper (Krzyścin and Baranowski 2019).…”

Short-term variability of total column ozone from the Dobson spectrophotometer measurements at Belsk, Poland, in the period 23 March 1963–31 December 2019

“…This data, divided into three subperiods (1963-1979, 1980-1999, and 2000-2019), has been stored at the PANGAEA data base (Rajewska-Wie R ch et al, 2020) with additional information including: time of observation, description of the wavelength pairs, and observation setting for each individual measurement. Splitting the data into three subsets corresponds to three phases of the TCO long-term variability: trendless, strong decline followed by strong recovery, and finally a weak recovery (Krzy scin and Baranowski, 2019).…”

“…Determining the onset of ozone regeneration in response to ODS changes has been the subject of extensive scientific debate based on the results of the statistical and chemistryclimate models (Reinsel et al, 2005;Harris et al, 2008;Morgenstern et al, 2010;Dhomse et al, 2018;Krzy scin and Baranowski, 2019). Clear signs of the Antarctic ozone recovery have recently been revealed (Solomon et al, 2016;Pazmiño et.…”
