“…The 30-mbar temperature is also included in the figure and illustrates a well-known observation that the upper stratospheric temperature appears highly correlated with total ozone under some atmospheric conditions. The measurements of total ozone using the ground-based Brewer spectrometer [Dorokhov, 1990;Kerr, 1990]…”

Simultaneous balloonborne measurements of ozone and polar stratospheric clouds (PSCs) were made over Heiss Island (80.5°N, 57.6°E) during the 1988–1989 winter. These soundings were supplemented with additional ozonesondes and meteorological information obtained from regular radiosondes and rocketsondes. The ozone measurements taken by themselves do not suggest a spring decrease in ozone over Heiss Island. However, a comparison with ozonesonde data from another location near the solar terminator can be interpreted as suggesting ∼20% ozone loss between 17.5 and 24 km in the outer vortex. This would roughly correspond to a loss of ∼10 Dobson units (DU) or 3–4% loss in total ozone column. Observed transport effects make the identification of true ozone loss considerably more difficult and uncertain. No statistically significant direct correlation in the vertical structure of PSCs and ozone near the center of the dark Arctic vortex was observed in the limited number of soundings.

The atmospheric ozone plays an important role in understanding of the processes occurring in the atmosphere and changes in the climate. Total ozone observations in Siberia were performed by Brewer MKIV No. 049 spectrophotometer in Tomsk, Western Siberia and SAOZ UV-Vis spectrometers deployed along the Arctic Circle in Salekhard aerological station since 1998 and Zhigansk aerological station in Eastern Siberia since 1991. We also use 2Z-ECC ozonesondes for ozone profile observations in winter–spring period at the Salekhard aerological station at the in Western Siberia and ECC-6A sondes at the drifting North Pole station NP-38 in the Central Arctic area. During the winter–spring season in 2011, Arctic ozone in the 19–21 km altitude region was observed to be more than 70% less that typical values. In the winter–spring of 2012, on the other hand, Arctic conditions were overall much warmer than in 2011, and no evidence of significant ozone loss was seen above the Asiatic regions of Russian Federation.

The aim of the paper is to describe which and where these measurements were carried out and illustrate their performances by some examples of ozone data measured in Western and Eastern Siberia, Russia such as that which occurred in the winter–spring season of 2011

“…Total ozone can be also derived from focused sun measurements, commonly employed at high latitudes (Josefsson, 1992). It is also possible to determine total ozone by using the moon as a light source (Kerr et al, 1990), or measuring the global spectral irradiance in the UV region (Kerr and Davis, 2007). The most accurate method for determining the total column amount of a gas in the atmosphere is based on the DS measurements.…”

Examination on total ozone column retrievals by Brewer spectrophotometry using different processing software

Abstract. The availability of long-term records of the total ozone content (TOC) represents a valuable source of information for studies on the assessment of short- and long-term atmospheric changes and their impact on the terrestrial ecosystem. In particular, ground-based observations represent a valuable tool for validating satellite-derived products. To our knowledge, details about software packages for processing Brewer spectrophotometer measurements and for retrieving the TOC are seldom specified in studies using such datasets. The sources of the differences among retrieved TOCs from the Brewer instruments located at the Italian stations of Rome and Aosta, using three freely available codes (Brewer Processing Software, BPS; O3Brewer software; and European Brewer Network (EUBREWNET) level 1.5 products) are investigated here. Ground-based TOCs are also compared with Ozone Monitoring Instrument (OMI) TOC retrievals used as an independent dataset since no other instruments near the Brewer sites are available. The overall agreement of the BPS and O3Brewer TOC data with EUBREWNET data is within the estimated total uncertainty in the retrieval of total ozone from a Brewer spectrophotometer (1 %). However, differences can be found depending on the software in use. Such differences become larger when the instrumental sensitivity exhibits a fast and dramatic drift which can affect the ozone retrievals significantly. Moreover, if daily mean values are directly generated by the software, differences can be observed due to the configuration set by the users to process single ozone measurement and the rejection rules applied to data to calculate the daily value. This work aims to provide useful information both for scientists engaged in ozone measurements with Brewer spectrophotometers and for stakeholders of the Brewer data products available on Web-based platforms.
