“…During day, NO 2 reacts rapidly to reform NO either by reaction with atomic oxygen (upper stratosphere) or photolysis: Wetzel et al, 2007;Kerzenmacher et al, 2008;Wolff et al, 2008). In this paper we focus on Arctic stratospheric mixing ratios of chlorine and nitrogen species which change quickly their concentration around the terminator between night and day.…”

Abstract. The winter 2009/2010 was characterized by a strong Arctic vortex with extremely cold mid-winter temperatures in the lower stratosphere associated with an intense activation of reactive chlorine compounds (ClO x ) from reservoir species. Stratospheric limb emission spectra were recorded during a flight of the balloon version of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS-B) from Kiruna (Sweden) on 24 January 2010 inside the Arctic vortex. Several fast limb sequences of spectra (in time steps of about 10 min) were measured from nighttime photochemical equilibrium to local noon allowing the retrieval of chlorine-and nitrogen-containing species which change rapidly their concentration around the terminator between night and day. Mixing ratios of species like ClO, NO 2 , and N 2 O 5 show significant changes around sunrise, which are temporally delayed due to polar stratospheric clouds reducing the direct radiative flux from the sun. ClO variations were derived for the first time from MIPAS-B spectra. Daytime ClO values of up to 1.6 ppbv are visible in a broad chlorine activated layer below 26 km correlated with low values (below 0.1 ppbv) of the chlorine reservoir species ClONO 2 . Observations are compared and discussed with calculations performed with the 3-dimensional Chemistry Climate Model EMAC (ECHAM5/MESSy Atmospheric Chemistry). Mixing ratios of the species ClO, NO 2 , and N 2 O 5 are well reproduced by the model during night and noon. However, the onset of ClO production and NO 2 loss around the terminator in the model is not consistent with the measurements. The MIPAS-B observations along with Tropospheric UltravioletVisible (TUV) radiation model calculations suggest that polar stratospheric clouds lead to a delayed start followed by a faster increase of the photodissoziation of ClOOCl and NO 2 near the morning terminator since stratospheric clouds alter the direct and the diffuse flux of solar radiation. These effects are not considered in the EMAC model simulations which assume a cloudless atmosphere.

Abstract. The Global Ozone Monitoring by Occultation of Stars (GOMOS) instrument onboard the European Space Agency's ENVISAT satellite measures ozone, NO 2 , NO 3 , H 2 O, O 2 , and aerosols using the stellar occultation method. Global coverage, good vertical resolution and the self-calibrating measurement method make GOMOS observations a promising data set for building various climatologies and time series. In this paper we present GOMOS nighttime measurements of ozone, NO 2 , and NO 3 during six years [2002][2003][2004][2005][2006][2007][2008]. Using zonal averages we show the time evolution of the vertical profiles as a function of latitude. In order to get continuous coverage in time we restrict the latitudinal region to 50 • S-50 • N. Time development is analysed by fitting constant, annual and semi-annual terms as well as solar and QBO proxies to the daily time series. Ozone data cover the stratosphere, mesosphere and lower thermosphere (MLT). NO 2 and NO 3 data cover the stratosphere. In addition to detailed analysis of profiles we derive total column distributions using the fitted time series.The time-independent constant term is determined with a good accuracy (better than 1%) for all the three gases. The median retrieval accuracy for the annual and semi-annual term varies in the range 5-20%. For ozone the annual terms dominate in the stratosphere giving early winter ozone maxima at mid-latitudes. Above the ozone layer the annual terms change the phase which results in ozone summer maximum up to 80 km. In the MLT the annual terms dominate up Correspondence to: E. Kyrölä (erkki.kyrola@fmi.fi) to 80 km where the semiannual terms start to grow. In the equatorial MLT the semi-annual terms dominate the temporal evolution whereas in the mid-latitude MLT annual and semiannual terms compete evenly. In the equatorial stratosphere the QBO dominates the time development but the solar term is too weak to be determined. In the MLT above 85 km the solar term grows significantly and ozone has 15-20% dependence on the solar cycle. For NO 2 below 32 km the annual summer maxima dominates at mid-latitudes whereas in the equatorial region a strong QBO prevails. In northern mid-latitudes a strong solar term appears in the upper stratosphere. For NO 3 the annual variation dominates giving rise to summer maxima. The NO 3 distribution is controlled by temperature and ozone.

“…The retrieval has a lower altitude limit of 6 km and an upper altitude limit of 107 km. ACE-FTS v2.2 NO was validated by Kerzenmacher et al (2008), and there were two known issues with the v2.2 results (still present in the v3.5 NO results). At altitudes below ∼ 20 km, NO VMRs suffer from a significant negative bias that causes many unphysical negative results.…”

“…To account for diurnal variations, calculations made using the "Pratmo" photochemical box model (McLinden et al, 2002) are used to scale local times between the two instruments. This model was used by Kerzenmacher et al (2008) in the validation of version 2.2 of the ACE-FTS (Atmospheric Chemistry Experiment -Fourier Transform Spectrometer) NO and NO 2 data. ACE-FTS level 2 version 3.5 data are used in comparison to coincident level 2 data from the satellite instruments Global Ozone Monitoring by Occultation of Stars (GO-MOS), Halogen Occultation Experiment (HALOE), Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO), Michelson Table 2.…”

Abstract. The ACE-FTS (Atmospheric Chemistry Experiment -Fourier Transform Spectrometer) instrument on the Canadian SCISAT satellite, which has been in operation for over 12 years, has the capability of deriving stratospheric profiles of many of the NO y (N + NO + NO 2 + NO 3 + 2 × N 2 O 5 + HNO 3 + HNO 4 + ClONO 2 + BrONO 2 ) species. Version 2.2 of ACE-FTS NO, NO 2 , HNO 3 , N 2 O 5 , and ClONO 2 has previously been validated, and this study compares the most recent version (v3.5) of these five ACE-FTS products to spatially and temporally coincident measurements from other satellite instruments -GOMOS, HALOE, MAE-STRO, MIPAS, MLS, OSIRIS, POAM III, SAGE III, SCIA-MACHY, SMILES, and SMR. For each ACE-FTS measurement, a photochemical box model was used to simulate the diurnal variations of the NO y species and the ACE-FTS measurements were scaled to the local times of the coincident measurements. The comparisons for all five species show good agreement with correlative satellite measurements. ForPublished by Copernicus Publications on behalf of the European Geosciences Union. 5782 P. E. Sheese et al.: Validation of ACE-FTS version 3.5 NO y species profiles NO in the altitude range of 25-50 km, ACE-FTS typically agrees with correlative data to within −10 %. Instrumentaveraged mean relative differences are approximately −10 % at 30-40 km for NO 2 , within ±7 % at 8-30 km for HNO 3 , better than −7 % at 21-34 km for local morning N 2 O 5 , and better than −8 % at 21-34 km for ClONO 2 . Where possible, the variations in the mean differences due to changes in the comparison local time and latitude are also discussed.
