Special Issue Information

Dear Colleagues,

The stratospheric ozone layer protects the Earth against harmful solar UV radiation and contributes to maintaining the vertical structure of temperature in the Earth’s atmosphere.

It plays a fundamental role in both terrestrial ecosystem and global climate. The study of the stratospheric ozone started in the early 20th century and intensified after the discovery of the “Ozone hole” over Antarctica and of an ozone depletion trend over large areas of our planet in the 1980s.

The phasing-out of ozone-depleting substances with the Montreal Protocol and subsequent amendments started the process of gradual recovery to pre-1980 stratospheric ozone levels. Direct evidence of the weakening of ozone depletion associated with the decline of chlorine species in the Antarctic stratosphere is now available from space-borne observations.

Nonetheless, interactions of chemistry and climate, coupled with atmospheric dynamical and radiative processes, greenhouse gases, and unregulated ozone-destroying emissions, can alter in a substantial manner the rate of ozone recovery. Accurate and continuous monitoring of stratospheric ozone on the global scale remains, therefore, a priority task.     

The topics of this Special Issue are related to stratospheric ozone and ozone-related species, with special emphasis on measurement, including:   

  • Observations of ozone vertical profile and column by means of remote sensing and in situ sensors from ground-based stations and airborne and spaceborne platforms
  • Response of stratospheric ozone to atmospheric dynamical processes
  • Impact of chemistry–climate interaction processes on stratospheric ozone
  • Effects of GHG and unregulated ozone-destroying emissions on ozone layer recovery
  • Stratospheric ozone, solar radiation, and their impact on ecosystems
  • Sensors and instrumentation for measuring stratospheric ozone and related parameters

AURORA (Advanced Ultraviolet Radiation and Ozone Retrieval for Applications) is a three-year project supported by the European Union in the frame of its H2020 Call (EO-2-2015) for “Stimulating wider research use of Copernicus Sentinel Data”. The project addresses key scientific issues relevant for synergistic exploitation of data acquired in different spectral ranges by different instruments on board the atmospheric Sentinels. A novel approach, based on the assimilation of geosynchronous equatorial orbit (GEO) and low Earth orbit (LEO) fused products by application of an innovative algorithm to Sentinel-4 (S-4) and Sentinel-5 (S-5) synthetic data, is adopted to assess the quality of the unique ozone vertical profile obtained in a context simulating the operational environment. The first priority is then attributed to the lower atmosphere with calculation of tropospheric columns and ultraviolet (UV) surface radiation from the resulting ozone vertical distribution. Here we provide details on the surface UV algorithm of AURORA. Both UV index (UVI) and UV-A irradiance are provided from synthetic satellite measurements, which in turn are based on atmospheric scenarios from MERRA-2 (Modern-Era Retrospective analysis for Research and Applications, Version 2) re-analysis. The UV algorithm is implemented in a software tool integrated in the technological infrastructure developed in the context of AURORA for the management of the synthetic data and for supporting the data processing. This was closely linked to the application-oriented activities of the project, aimed to improve the performance and functionality of a downstream application for personal UV dosimetry based on satellite data. The use of synthetic measurements from MERRA-2 gives us also a “ground truth”, against which to evaluate the performance of our UV model with varying inputs. In this study we both describe the UV algorithm itself and assess the influence that changes in ozone profiles, due to the fusion and assimilation, can cause in surface UV levels. Full article

This study aims to compare the ground-based Brewer spectrophotometer total ozone column measurements with the Dobson spectrophotometer and various satellite overpass data available at Marambio Base during the period 2011–2013. This station provides a unique opportunity to study ozone variability near the edge of the southern polar vortex; therefore, many institutions, such as the National Meteorological Service of Argentina, the Finnish Meteorological Institute and the Czech Hydrometeorological Institute, have been carrying out various scientific activities there. The intercomparison was performed using total ozone column data sets retrieved from the ground-based instruments and from Ozone Monitoring Instrument (OMI)—Total Ozone Mapping Spectrometer (TOMS), OMI–Differential Optical Absorption Spectroscopy (DOAS), Global Ozone Monitoring Experiment 2 (GOME2), and Scanning Imaging Absorption Spectrophotometer for Atmospheric Cartography (SCIAMACHY) satellite observations. To assess the quality of the selected data products, comparisons with reference to the Brewer spectrophotometer single observations were made. The performance of the satellite observational techniques was assessed against the solar zenith angle and effective temperature, as well as against the actual shape of the vertical ozone profiles, which represent an important input parameter for the satellite ozone retrievals. The ground-based Dobson observations showed the best agreement with the Brewer data set (R2 = 1.00, RMSE = 1.5%); however, significant solar zenith angle (SZA) dependency was found. The satellite overpass data confirmed good agreement with the Brewer observations but were, however, overestimated in all cases except for the OMI(TOMS), when the mean bias differed from −0.7 DU in the case of the OMI(TOMS) to 6.4 DU for the SCIAMACHY. The differences in satellite observational techniques were further evaluated using statistical analyses adapted for depleted and non-depleted conditions over the ozone hole period. Full article
