“…The simulated maximum amplitude at around 30 hPa (~24 km) of about 10 % in relative value (anomaly divided by its climatology), from +0.6 to -0.4 ppmv in abundance range, below the phase transition is slightly smaller than observations. The amplitude of about 4 % (~0.4 ppmv) at around 10 hPa (~31 km in the model) above the phase transition is very similar to the observed values of about 5 % at 31 km (Zawodny and McCormick, 1991;Chipperfield et al, 1994;Hauchecorne et al, 2010). While the O3 amplitude below 50 hPa is small in absolute values, it is much larger in relative values (not shown due to out of scale) than that at 30 hPa, being consistent with GOMOS data (Hauchecorne et al, 2010).…”

“…The model reproduces the phase transition of the ozone QBO from dynamical to photochemical control at around 28 km (~18 hPa) in observations by SAGE II (e.g., Zawodny and McCormick, 1991;Chipperfield et al, 1994) and GOMOS (Hauchecorne et al, 2010), resulting in a dogleg-shape pattern with a vertex slightly above 20 hPa in the ozone anomaly.…”

“…Along with the QBO in dynamical quantities, trace gases such as ozone show similar oscillations in the equatorial stratosphere due to the transport and/or chemistry associated with the QBO, and the corresponding ozone oscillation is thereby called the ozone QBO. Detailed vertical and temporal structures of the QBO in O3 and NO2 were revealed through Stratospheric Aerosol and Gas Experiment (SAGE) II data by Zawodny and McCormick (1991), Hasebe (1994), and Chipperfield et al (1994), and through Global Ozone Monitoring by Occultation of Stars (GOMOS) data by Hauchecorne et al (2010) and Liu et al (2011). Also Park et al (2017) showed the detailed structures of the QBO in O3, NOx, N2O, and HNO3 by analyzing Optical Spectrograph and Infrared Imager System (OSIRIS) data.…”

Ozone loss pathways and their rates in the ozone quasi-biennial oscillation (QBO) simulated by a chemistry-climate model of the Meteorological Research Institute of Japan are evaluated by using an objective pathway analysis program (PAP). The analyzed chemical system contains catalytic cycles due to NOx, HOx, ClOx, Ox, and BrOx. PAP quantified the rates of all significant catalytic ozone loss cycles, and evaluated the partitioning among these cycles. The QBO amplitude of the sum of all cycles amounts to about 4 and 14 % of the annual mean of the total ozone loss rate at 10 and 20 hPa, respectively. The contribution of catalytic cycles to the QBO of the ozone loss rate is found to be as follows: NOx cycles contribute the largest fraction (50-85 %) of the QBO amplitude of the total ozone loss rate; HOx cycles are the second-largest (20-30 %) below 30 hPa and the third-largest (about 10 %) above 20 hPa; Ox cycles rank third (5-20 %) below 30 hPa and second (about 20 %) above 20 hPa; ClOx cycles rank fourth (5-10 %); and BrOx cycles are almost negligible. The relative contribution of the NOx and Ox cycles to the QBO amplitude of ozone loss differs by up to 10 and 20 %, respectively, from their contribution to the annual-mean ozone loss rate. The ozone QBO at 20 hPa is mainly driven by ozone transport, which then affects the ozone loss rate. In contrast, the ozone QBO at 10 hPa is driven chemically mainly by NOx and the temperature dependence of [O]/[O3], which results from the temperature dependence of the reaction O + O2 + M → O3 + M. In addition, the ozone QBO at 10 hPa is influenced by the overhead ozone column, which affects [O]/[O3] (through ozone photolysis) and the ozone production rate (through oxygen photolysis).

“…It is possibly not the case in reality, if volcanoes, solar activity or other sporadic factors are also playing a role in the ozone budget. For instance, the influence of Quasi Biennal Oscillation (QBO) on ozone was shown to depend on altitude: Hauchecorne et al (2010) found three different regions with different influences. Also, the period of QBO is not fixed, and regression may be inaccurate.…”

“…In a companion paper of this GOMOS ACP issue, Hauchecorne et al (2010) have investigated the impact of the Quasi-Biennial Oscillation (QBO) of the equatorial wind on the inter-annual variations of ozone and NO 2 . A six years period of GOMOS data from August 2002 to December 2008 recorded between 15 • S and 15 • N was analysed, first by establishing a seasonal mean, and then dividing all data by this seasonal mean.…”

Abstract. GOMOS on ENVISAT (launched in February, 2002) is the first space instrument dedicated to the study of the atmosphere of the Earth by the technique of stellar occultations (Global Ozone Monitoring by Occultation of Stars). Its polar orbit makes good latitude coverage possible. Because it is self-calibrating, it is particularly well adapted to long time trend monitoring of stratospheric species. With 4 spectrometers, the wavelength coverage of 248 nm to 942 nm enables monitoring ozone, H 2 O, NO 2 , NO 3 , air density, aerosol extinction, and O 2 . Two additional fast photometers (with 1 kHz sampling rate) enable the correction of the effects of scintillations, as well as the study of the structure of air density irregularities resulting from gravity waves and turbulence. A high vertical resolution profile of the temperature may also be obtained from the time delay between the red and the blue photometer. Noctilucent clouds (Polar Mesospheric Clouds, PMC) are routinely observed in both polar summers and global observations of OClO and sodium are achieved.The instrument configuration, dictated by the scientific objectives' rationale and technical constraints, is described, together with the typical operations along one orbit, along with the statistics from over 6 years of operation. Typical atmospheric transmission spectra are presented and some retrieval difficulties are discussed, in particular for O 2 and H 2 O.Correspondence to: J. L. Bertaux (bertaux@latmos.ipsl.fr) An overview is presented of a number of scientific results already published or found in more detail as companion papers in the same ACP GOMOS special issue. This paper is particularly intended to provide an incentive for the exploitation of GOMOS data available to the whole scientific community in the ESA data archive, and to help GOMOS data users to better understand the instrument, its capabilities and the quality of its measurements, thus leading to an increase in the scientific return.

Changes in the composition of the northern polar upper stratosphere in February 2009 after a sudden stratospheric warming

. This suggests that the very low temperatures favor a more effective ozone production and a greater O 3 /O ratio. The latter is the main factor controlling active chlorine partitioning. Increases of ClO lead to high ClONO 2 concentrations in the upper stratosphere at high latitudes, where its photodissociation rate is smaller. Since this increase of ClONO 2 happens at the expense of HCl, the region of high ClONO 2 roughly coincides with the region of low HCl. Although this period was characterized by an elevated stratopause event, the investigated region was not influenced by the descent of mesospheric air rich in NO x . Some limited enhancements in NO x at~1 hPa occurred at latitudes greater than 80°N after about 20 February, but they became consistent only in March. Intrusion of midlatitude air mostly occurred between the SSW and early February. Then, the sum of volume mixing ratios of ClONO 2 + ClO + HCl remained approximately constant and close to the values of the other years. In contrast, it was up to 0.2 ppbv lower during the SSW period. These atypical chemical conditions occurred also in February 2006, but 2009 stands out for its long-lasting effects, which persisted until late March.
