BACKGROUND Tomato is sensitive to ozone. Fruit growth and composition are altered under ozone stress by modification of reproductive development. Fifty-one-day-old plants were exposed to three concentrations of ozone (200, 350 and 500 µg m(-3)) for 4 h. RESULTS Ozone reduced well-developed fruit number and fruit size, but it did not significantly affect flowering rate and fruit setting rate. ...

8 years of ERS-2/GOME total ozone observations are used to evaluate first results of a multi-year model simulation representing "year 2000" conditions with an updated version of the coupled-chemistry climate model ECHAM4.L39(DLR)/CHEM (hereafter: E39/C). The analysis focuses on zonal large scale variations of corresponding ozone fields. We present a comparison of total ozone and wave amplitudes...

Over the last 3 decades, satellite data have been used to monitor long-term global changes in stratospheric ozone. The TOMS series (1978–present) and GOME (1995– present) are two very important instruments in this context. In this paper, TOMS total ozone and three approaches to derive total ozone from GOME measurements are validated with ground-based Dobson network data. Beyond the operational ...

Total ozone anomalies (deviation from the long-term mean) are created by anomalous circulation patterns. The dynamically produced ozone anomalies can be estimated from known circulation parameters in the layer between the tropopause and the middle stratosphere by means of statistics. Satellite observations of ozone anomalies can be compared with those expected from dynamics. Residual negative a...

We investigate the extent to which quantities that are based on total column ozone are applicable as measures of ozone loss in the polar vortices. Such quantities have been used frequently in ozone assessments by the World Meteorological Organization (WMO) and also to assess the performance of chemistry-climate models. The most commonly considered quantities are March and October mean column oz...

Background and Objective: Skin ulcers and their slow healing are considered as one of the important medical aspects. Nowadays, various antibiotics and materials are used to accelerate the wound healing process. One of the methods taken in the field of wound healing is using ozone. On the other hand, one of the factors that hurt the speed of wound healing is stress. Therefore, the present study ...
