“…In the first quarter of 2016, three short-term periods with significantly lower daily TOCs, compared to the climatologically averaged values for the period from 1979 to 2017, were observed over the territory of Russia. TOC decreases reached 39 %-52 % (on 26 January-1 February 2016 over the northern regions of the Urals and Siberia), 30 %-50 % (on 20 February-3 March 2016 over northern Siberia), and 27 %-39 % (on 9-19 March 2016 over central Siberia) of daily averaged values of ozone column (191-257, 227-321, and 257-321 DU for these three periods) (Zvyagintsev et al, 2016 Figure 1 taken from Garkusha et al (2018) depicts the spatial distribution of TOCs on 23-27 February 2016, based on measurements of the two instruments of the same type IKFS-2 and IASI. The figure shows good agreement between these two independent satellite measurements.…”

Episodes of extremely low ozone columns were observed over the territory of Russia in the Arctic winter of 2015/2016 and the beginning of spring 2016. We compare total ozone columns (TOCs) from different remote sensing techniques (satellite and ground-based observations) with results of numerical modelling over the territory of the Urals and Siberia for this period. We demonstrate that the provided monitoring systems (including the new Russian Infrared Fourier Spectrometer IKFS-2) and modern threedimensional atmospheric models can capture the observed TOC anomalies. However, the results of observations and modelling show differences of up to 20 %-30 % in TOC measurements. Analysis of the role of chemical and dynamical processes demonstrates that the observed short-term TOC variability is not a result of local photochemical loss initiated by heterogeneous halogen activation on particles of polar stratospheric clouds that formed under low temperatures in the mid-winter.

Extremely low winter TOC values (episodically less than the mini-hole threshold) were observed over the northern regions of the Urals and Siberia for the first time.…”

“…Unusually sharp and repetitive TOC loss was observed over the territory of the Urals and Siberia in the first quarter of 2016. In some cases, the TOC loss reached 40 %-50 % in comparison with climatic values (Zvyagintsev et al, 2016).…”

“…Extremely low values of total ozone columns (TOCs) were recorded in January-February 2016 in the polar region of the Northern Hemisphere (Zvyagintsev et al, 2016;Manney and Lawrence, 2016). Observed low values were recorded long before the beginning of spring, when chemical destruction of ozone occurs periodically in the Northern Hemisphere as a result of a strong vortex and the long existence of polar stratospheric clouds (PSCs) (Manney et al, 2011).…”

Abstract. Episodes of extremely low ozone columns were observed over the territory of Russia in the Arctic winter of 2015/2016 and the beginning of spring 2016. We compare total ozone columns (TOCs) from different remote sensing techniques (satellite and ground-based observations) with results of numerical modelling over the territory of the Urals and Siberia for this period. We demonstrate that the provided monitoring systems (including the new Russian Infrared Fourier Spectrometer IKFS-2) and modern three-dimensional atmospheric models can capture the observed TOC anomalies. However, the results of observations and modelling show differences of up to 20 %–30 % in TOC measurements. Analysis of the role of chemical and dynamical processes demonstrates that the observed short-term TOC variability is not a result of local photochemical loss initiated by heterogeneous halogen activation on particles of polar stratospheric clouds that formed under low temperatures in the mid-winter.

Abstract. Episodes of extremely low ozone columns were observed over the territory of Russia in the Arctic winter of 2015/2016 and the beginning of spring 2016. We compare total ozone columns (TOC) obtained using different remote 10 sensing techniques (satellite and ground-based observations) and results of numerical modelling over the territory of the Urals and Siberia for the above period. We demonstrate that the provided monitoring systems (including new Russian Fourier-spectrometer IKFS-2) and modern 3-dimensional models are able to capture the observed TOC anomalies.However, the results of observations and modelling show discrepancies of up to 20-30% in TOC measurements. Analysis of the role of chemical and dynamical processes demonstrates that it is unlikely that observed short-term TOC variability may 15 be a result of local photochemical destruction initiated by heterogeneous halogen activation on particles of polar stratospheric clouds that formed under low temperatures in the mid-winter.
