Abstract

This paper presents results of stratospheric water vapor measurements made from balloon borne instruments in the arctic winter as a part of EASOE. A frost-point hygrometer allowed measurement of the frost point and air temperature, which allowed the detection of conditions consistent with the formation of polar stratospheric clouds. Such clouds were observed on one occasion when this diagnostic sensed conditions conducive to the formation of such clouds. Outside the polar vortex the average water vapor density was fairly constant, between 4 to 5 ppmv between 16 and 25 km. More variation was observed both above and below these altitudes, and inside the vortex, vertical motion was also observed.

Stratospheric water vapor measurements during CHEOPS-3. [CHemistry of Ozone in the Polar Stratosphere]

Journal Article Ovarlez, J - Geophysical Research Letters (American Geophysical Union); (United States)

During January 1990, in situ stratospheric water vapor measurements were performed over the Arctic during the CHEOPS experiment at Kiruna. The instrument used is a balloon-borne frost-point hygrometer. Results of two flights are shown: one of the flights showed thermal structure indicative of cooling induced by orographic forcing and favorable to PSC formation. Mixing ratio were the same for the two flights, 4-5 ppmv between 12 and 22 km. However, above 22 km, an increase in mixing ratio to 7.5 ppmv is observed. Because this increase is much higher than at mid-latitudes, the authors examine it in detail.

Some results of water vapor, ozone and aerosol balloon borne measurements during EASOE

Journal Article Khattatov, V; Yushkov, V; Khaplanov, M; ... - Geophysical Research Letters (American Geophysical Union); (United States)

As part of the European Arctic Stratospheric Ozone Experiment (EASOE) in the northern winter of 1991/92, regular measurements of the vertical distribution of ozone and aerosols were carried out from two Russian polar stations, Heiss Island (81N, 58E) and Dikson Island (73N, 81E). In addition measurements of the vertical distribution of water vapor and aerosols were made from Esrange (68N, 21E), near Kiruna in Sweden. The instruments used were electrochemical ozone sondes (ECC-4A), a fluorescence hygrometer, and the University of Wyoming backscattersonde. Following the eruption of Mt. Pinatubo, in the Philippines, in June 1991, volcanic aerosol had reached Arctic latitudesmore »« less

Balloon borne observations of backscatter, frost point and ozone in polar stratospheric clouds at the South Pole

Journal Article Rosen, J; Kjome, N; Oltmans, S - Geophysical Research Letters (American Geophysical Union); (United States)

Concurrent backscatter and ozone measurements were made with near-simultaneous frost point soundings over the South Pole when the center of the 1990 winter vortex was at or very near that location. The initial water vapor concentration in the stratosphere was {approximately}5ppmv and decreased to {approximately}1.5-2.0 ppmv as cooling took place. By mid-July the stratospheric temperature had decreased to the frost point and heavy polar stratospheric cloud (PSC) activity was observed presumably due to the condensation of water vapor. The lowest water vapor concentrations observed correspond to saturated air at the lowest temperatures encountered. The slow recovery of the water vapormore »« less

Simultaneous balloonborne measurements of stratospheric water vapor and ozone in the polar regions

Journal Article Hofmann, D; Oltmans, S; Deshler, T - Geophysical Research Letters (American Geophysical Union); (United States)

Vertical profiles of stratospheric water vapor and ozone were measured together at McMurdo and South Pole Stations in Antarctica, and at Kiruna, Sweden, on several occasions during the austral spring of 1990 and the boreal winter of 1991. The Antarctic data indicated that major dehydration had occurred on a continental scale over the winter stratospheric cloud formation period leaving only 2 to 3 ppmv water vapor between 11 and 19 km. Measurements before and after movement of the boundary of the polar vortex across McMurdo detected increases in both water vapor and ozone in the 17 to 20 km region.more »« less

The lifetime of leewave-induced ice particles in the Arctic stratosphere: I. Balloonborne observations

Journal Article Deshler, T; Peter, T; Mueller, R; ... - Geophysical Research Letters (American Geophysical Union); (United States)

During the European Arctic Stratospheric Ozone Experiment (EASOE) in 1991/1992 there were only a few occasions when polar stratospheric clouds (PSCs) were observed. One of these was on 27 January 1992 when PSCs were detected by two balloonborne aerosol instruments released from Esrange near Kiruna, Sweden (68[degrees]N). High concentrations of particles were found at altitudes between 19 and 24 km, in a series of many very thin layers. Particles as large as 5 [mu]m were detected. The surface area concentration in the densest layers exceeded 100 [mu]m[sup 2] cm[sup [minus]3], as estimated from retrieved size distributions. Estimates of the totalmore »« less
