“…Additionally the CRISTA-1 nighttime data show a mixing ratio maximum above 80 km at the equator. These features are also present in the MAS nighttime ozone data [Bevilacqua et al, 1996]. The CRISTA-2 nighttime data above 70 km shows much higher values at high southern latitudes: Between 70°S and 10°N the ozone VMR at polar latitudes is increased by a factor of 5 -10 (80 km), 3 (85 km) and 2 (90 km).…”

“…Ground-based microwave spectrometry was applied by Wilson and Schwartz [1981], Zommerfelds et al [1989], Connor et al [1994] and references cited therein. Spaceborne measurements of ozone microwave emissions were carried out by Froidevaux et al [1996] and Bevilacqua et al [1996]. Ozone in the upper mesosphere and lower thermosphere (UMLT) was also measured by rocket borne mass spectrometers [Trinks, 1975] and by the analysis of the duration distribution of overdense radio meteor echoes [Jones et al, 1990;Cevolani et al, 1999].…”

[1] The global distribution of mesospheric and lower thermospheric ozone 9.6 mm infrared emissions was measured by the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) experiment during two Space Shuttle missions in November 1994 and August 1997. The radiances measured by CRISTA have been inverted to O 3 number densities in the 50-95 km range by using a nonlocal thermodynamic equilibrium model. A detailed sensitivity study of retrieved O 3 number densities has been carried out. The ozone abundance profiles show volume mixing ratios of 1-2 ppmv at the stratopause, 0.5 ppmv or less around 80 km, and typically 1 ppmv during daytime and 10 ppmv during nighttime at the secondary maximum. The agreement with other experiments is typically better than 25%. The global distribution of upper mesospheric ozone shows significant latitudinal gradients and an enhancement in the equatorial upper mesosphere. At the polar night terminator a third ozone maximum is observed. Three-dimensional model results indicate that the latitudinal gradients are significantly influenced by solar tides.

“…There is no earlier comprehensive MLT nighttime ozone climatology from other satellite instruments. The validation of results above need to be based on the case by case comparisons with a few earlier nighttime MLT measurements [e.g., Bevilacqua et al , 1996; Zhou et al , 1998; Kaufmann et al , 2003], presently flying MIPAS, MLS and SABER instruments (see introduction for references), and models [e.g., Smith and Marsh , 2005]. This work will be performed in the future.…”

Nighttime ozone profiles in the stratosphere and mesosphere by the Global Ozone Monitoring by Occultation of Stars on Envisat

et al. 2006

[1] The Global Ozone Monitoring by Occultation of Stars (GOMOS) instrument on board the European Space Agency's Envisat satellite measures ozone and a few other trace gases 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. In this paper we present the nighttime stratospheric ozone distribution measured by GOMOS in 2003. We show monthly latitudinal distributions of the ozone number density and mixing ratio profiles, as well as the seasonal variations of profiles at several latitudes. The stratospheric profiles are compared with the Fortuin-Kelder daytime ozone climatology. Large differences are found in polar areas and they can be shown to be correlated with large increases of NO 2 . In the upper stratosphere, ozone values from GOMOS are systematically larger than in the Fortuin-Kelder climatology, which can be explained by the diurnal variation. In the middle and lower stratosphere, GOMOS finds a few percent less ozone than Fortuin-Kelder. In the equatorial area, at heights of around 15-22 km, GOMOS finds much less ozone than Fortuin-Kelder. For the mesosphere and lower thermosphere, there has previously been no comprehensive nighttime ozone climatology. GOMOS is one of the first new instruments able to contribute to such a climatology. We concentrate on the characterization of the ozone distribution in this region. The monthly latitudinal and seasonal distributions of ozone profiles in this altitude region are shown. The altitude of the mesospheric ozone peak and the semiannual oscillation of the number density are determined. GOMOS is also able to determine the magnitude of the ozone minimum around 80 km. The lowest seasonal mean mixing ratio values are around 0.13 ppm. The faint tertiary ozone peak at 72 km in polar regions during wintertime is observed.

“…From the measurements, latitudinal distributions of stratospheric C10 [Aellig et al, 1996], as well as stratospheric and mesospheric profiles of O3 and H20 have been derived [Bevilacqua et al, 1996;Daehler et al, 1998]. It should be pointed out that the MAS observations did not aim at the high latitudes.…”
