From long-term observations of ozone evolution in the stratosphere of the Kola Peninsula in the 2002/2003 winter, the rates of chemical destruction of ozone and its net loss at isentropic levels of 530 K (an altitude of about 22 km) and 465 K (an altitude of about 19 km) ar evaluated with consideration for diabatic descent of air masses. These rates were ?18.6±3.3 and ?14.3±2.9 ppb/day and the net loss of ozone due to its chemical destruction over the period from December 1, 2002, to March 5, 2003, reached 1.77±0.33 ppm and 1.36±0.29 ppm, respectively. At the lower level, these data are in satisfactory agreement (to within measurement errors) with other measurements that were taken at that time. At a potential-temperature level of 530 K, the ozone loss in the 2002/2003 season evaluated from our data and from similar microwave measurements performed in Kiruna (Sweden) virtually coincides and testifies to the fact that the net loss increases with altitude. These inferences are inconsistent with the results obtained with the Match technique and the method of averaging over a vortex, which indicate that the ozone loss decreases with altitude. However, since polar stratospheric clouds were detected regularly in December and early January at levels up to 600 K or higher, it may be suggested that the ozone loss at these altitudes can be comparable to the values found for isentropic levels of 465 to 475 K. 相似文献

We present the results of microwave observations of the ozone content variability in the upper stratosphere and lower mesosphere during a total solar eclipse of March 29, 2006 at the Kislovodsk high-altitude scientific station. An increase in the concentration of mesospheric ozone was recorded during the eclipse. At a height of 60 km, the ozone concentration increased by 40%, which is close to the value of diurnal ozone variations. 相似文献

As a result of the long-term observations lead in region of Kola Peninsula, connection between character of variations of
the ozone content in a stratosphere of Arctic regions and behavior and structure of a winter polar vortex is established.
During winter seasons with well developed cyclone and duration of stable existence not less than 1.5–2 months were observed
extremely low ozone number density at heights 20–25 km connected, apparently, with its chemical destruction. On the other
hand, during disturbances of the vortex, accompanied strong stratospheric warming, was registered almost double increase of
ozone amount in a high-altitude interval from 20 up to 40 km. Comparison of results of ground-based microwave monitoring of
an ozone layer to data of the satellite instrument EOS MLS installed on satellite AURA is lead. In most cases comparison has
shown satisfactory within the limits of an error of measurements coincidence of results. However in conditions of atmospheric
disturbances when arose significant spatial heterogeneity, the discrepancy of results of comparison was marked. The possible
reasons which cause the detected disagreement in results are discussed. 相似文献

We present the results of simultaneous measurements of variations in the ozone layer in the north-western Arctic conducted with the help of different instruments. It is shown that, in the winter of 2003–2004, when the stratosphere was relatively warm and the wave activity was high, spatial inhomogeneities in the field of ozone distribution were observed. For April 2004, we detect a decrease in the ozone content in the range of heights between 25 and 40 km. This decrease was recorded simultaneously by the HALOE, SAGE, and POAM satellite instruments. 相似文献

Presented are the results of studying the ozone layer over Nizhni Novgorod and Central Asia using the ground-based millimeter wavelength range equipment. Carried out is the comparison of results of ground-based measurements with the EOS Aura MLS data. The difference in the ozone layer structure at stratospheric heights is revealed during the joint measurements at the mentioned points in November 2010. The analysis demonstrates that this difference is caused by the influence of the polar stratospheric vortex. Proceeding from the experience of similar researches, the conclusion is made on the necessity of organizing the permanent domestic network of the ground-based microwave monitoring of the ozone layer. 相似文献

Response of mesospheric ozone to the heating of the lower ionosphere by high-power HF radio emission
Yu. Yu. Kulilov V. L. Frolov G. I. Grigor’ev V. M. Demkin G. P. Komrakov A. A. Krasilnokov V. G. Ryskin 《Geomagnetism and Aeronomy》2013,53(1):96-103
We detected a decrease in the intensity of microwave radiation at the atmospheric ozone line at a frequency of 110836.04 MHz during ionospheric modification by high-power HF radiowaves radiated by the Sura Ionospheric Heating Facility. The obtained experimental data allowed us to hypothesize that this effect was caused by the fact that mesospheric ozone was affected by internal gravity waves generated in the E region of the ionosphere during its high-power HF radiowave heating. 相似文献
