Floral bullseyes and stratospheric ozone
Current Biology, 2021As well as guiding pollinators to the centre of flowers, areas of the corolla that absorb UV radiation may help to protect floral reproductive parts from solar UV radiation that would otherwise be reflected onto them. In their recent article, 'Floral pigmentation has responded rapidly to global change in ozone and temperature', Koski et al.1 compared ...

Wildfire smoke destroys stratospheric ozone
Science, 2022Large wildfires inject smoke and biomass-burning products into the mid-latitude stratosphere, where they destroy ozone, which protects us from ultraviolet radiation. The infrared spectrometer on the Atmospheric Chemistry Experiment satellite measured the spectra of smoke particles from the “Black Summer” fires in Australia in late 2019 and early 2020 ...

Science, 1993
This paper is a review of research and present knowledge on ozone layer losses during the winter in the Arctic and Antarctic. Heterogeneous chemical reactions in polar stratospheric clouds and sulfate aerosols are discussed. Methods for determining actual ozone losses are discussed, with particular emphasis on the Arctic ozone layer.

Measured Trends in Stratospheric Ozone
Science, 1992Recent findings, based on both ground-based and satellite measurements, have established that there has been an apparent downward trend in the total column amount of ozone over mid-latitude areas of the Northern Hemisphere in all seasons. Measurements of the altitude profile of the change in the ozone concentration have established that decreases are ...

The Ozone Dynamics in the Stratosphere
Revista de Chimie, 2008This work studies the O3 dynamics in the stratosphere by taking into consideration the reactions of Chapman s model, the reactions of the O3 consuming catalytic cycles by the species HOx, ClOx and NOx and the coupling reactions between these species.

The stratospheric ozone layer—An overview
Environmental Pollution, 1994This paper summarises the knowledge on the properties of the stratospheric ozone layer. Dynamic, chemical, and microphysical aspects are reviewed with emphasis on chemistry. The questions addressed are as follows. Do we have a quantitative understanding of the Antarctic ozone hole?

Stratospheric Ozone Effects on Temperature
Science, 1976Calculated surface temperature changes, ΔT 8 , due to stratospheric ozone depletion (at 35°N latitude in April) are less than previously estimated and range between –0.6 and +0.9°K. The sign of ΔT 8 is determined by the surface albedo and the presence or absence of a low-lying particulate ...
