Special Issue Information

Dear Colleagues,

Ozone is a very important trace gas in the stratosphere because its protects biota from harmful solar radiation. The amount of ozone is given not only by ozone chemistry but also by stratospheric dynamics. Nowadays, the concentration of ozone-depleted substances is decreasing, which has a positive impact on the ozone concentration. On the other hand, the stratospheric dynamics are influenced by global warming, which plays an important role in the behavior of ozone in the stratosphere. We also observe the acceleration of Brewer–Dobson circulation, which transports the ozone from the tropics to a polar latitude together with a decrease in stratospheric temperatures due to global warming. An increase in tropopause height is also present. Changes in the propagation of planetary waves are seen in the stratosphere. The recovery of the ozone layer is expected in the future, but its date is uncertain depending on the model used. There are also model differences, which could be the matter of research. Stratospheric dynamics also have an influence on the troposphere, so vertical coupling between the troposphere and stratosphere is observed.

All of these phenomena lead to an interesting situation in the behaviour of the stratospheric ozone; this behaviour will be the central topic of a Special Issue of Atmosphere. The basic topics of this Special Issue are the following: the relationship between ozone chemistry and dynamics in the statosphere, the influence of ozone to statosphere–troposphere coupling, and the influence of global warming on the stratospheric dynamics and ozone concentration.  Similar topics are also suitable for this Special Issue.

The recovery and re-calibration of a dataset of vertical aerosol extinction profiles of the 1963/64 stratospheric aerosol layer measured by a searchlight at 32° N in New Mexico, US, is reported. The recovered dataset consists of 105 aerosol extinction profiles at 550 nm that cover the period from December 1963 to December 1964. It is a unique record of the portion of the aerosol cloud from the March 1963 Agung volcanic eruption that was transported into the Northern Hemisphere subtropics. The data-recovery methodology involved re-digitizing the 105 original aerosol extinction profiles from individual Figures within a research report, followed by the re-calibration. It involves inverting the original equation used to compute the aerosol extinction profile to retrieve the corresponding normalized detector response profile. The re-calibration of the original aerosol extinction profiles used Rayleigh extinction profiles calculated from local soundings. Rayleigh and aerosol slant transmission corrections are applied using the MODTRAN code in transmission mode. Also, a best-estimate aerosol phase function was calculated from observations and applied to the entire column. The tropospheric aerosol phase function from an AERONET station in the vicinity of the searchlight location was applied between 2.76 to 11.7 km. The stratospheric phase function, applied for a 12.2 to 35.2 km altitude range, is calculated from particle-size distributions measured by a high-altitude aircraft in the vicinity of the searchlight in early 1964. The original error estimate was updated considering unaccounted errors. Both the re-calibrated aerosol extinction profiles and the re-calibrated stratospheric aerosol optical depth magnitudes showed higher magnitudes than the original aerosol extinction profiles and the original stratospheric aerosol optical depth, respectively. However, the magnitudes of the re-calibrated variables show a reasonable agreement with other contemporary observations. The re-calibrated stratospheric aerosol optical depth demonstrated its consistency with the tropics-to-pole decreasing trend, associated with the major volcanic eruption stratospheric aerosol pattern when compared to the time-coincident stratospheric aerosol optical depth lidar observations at Lexington at 42° N.
