Is the ozone hole over your classroom?
First year university science students are surveyed about their understanding of the ozone layer, ozone depletion and the effect of ozone depletion on Australia. Although students seem to understand the basic function of the ozone layer, over 65% of students incorrectly believe that the ozone hole is over Australia, and over 90% of students incorrectly believe that the ozone hole is present dur...
متن کاملAn Overview of the Scientific Aspects of Ozone Depletion and Their Impact on the Environment
This paper describes the protective action of stratospheric ozone together with different mechanisms causing ozone depletion. Ozone absorbs UV radiation coming from the Sun. Increased UV radiation due to ozone depletion affects people, terrestrial and aquatic ecosystems, materials as well as air quality. Chlorofluorocarbons, halons and methyl bromide are all significant ozone depleting substanc...
متن کاملCould stratospheric ozone depletion lead to enhanced aquatic primary production in the polar regions?
We study the effects of ozone depletion on primary production in ice-covered and open polar waters using a spectral radiative transfer model combined with a parameterization of the inhibition of marine photosynthesis by ultraviolet radiation. We find that ozone depletion might not have a negative influence on the aquatic algal community at high latitudes but instead could enhance primary produc...
متن کاملStratospheric Ozone Depletion: a Review of Concepts and History
Stratospheric ozone depletion through catalytic chemistry involving man-made chlorofluorocarbons is an area of focus in the study of geophysics and one of the global environmental issues of the twentieth century. This review presents a brief history of the science of ozone depletion and describes a conceptual framework to explain the key processes involved, with a focus on chemistry. Observatio...
متن کاملContrasts between Antarctic and Arctic ozone depletion.
This work surveys the depth and character of ozone depletion in the Antarctic and Arctic using available long balloon-borne and ground-based records that cover multiple decades from ground-based sites. Such data reveal changes in the range of ozone values including the extremes observed as polar air passes over the stations. Antarctic ozone observations reveal widespread and massive local deple...
متن کاملComparison of three vertically resolved ozone data sets: climatology, trends and radiative forcings
Climate models that do not simulate changes in stratospheric ozone concentrations require the prescription of ozone fields to accurately calculate UV fluxes and stratospheric heating rates. In this study, three different global ozone time series that are available for this purpose are compared: the data set of Randel and Wu (2007) (RW07), Cionni et al. (2011) (SPARC), and Bodeker et al. (2013) ...
