Science, 1976
Balloons and U-2 aircraft were used to collect micrometer-sized stratospheric aerosols. It was discovered that for the past 6 years at least, aluminum oxide spheres have been the major stratospheric particulate in the size range 3 to 8 micrometers. The most probable source of the spheres is the exhaust from solid-fuel rockets.

Stratospheric Hydroperoxyl Measurements
Science, 1990The hydroperoxyl radical (HO 2 ) plays a key role in stratospheric chemistry through the HO x catalytic cycle of ozone destruction. Earlier measurements of stratospheric HO 2 have given mixed results; some measured mixing ratios greatly ...

Stratosphere-troposphere interactions
Herald of the Russian Academy of Sciences, 2015This article is devoted to the most topical trends in stratosphere-troposphere interaction and its influence on the climate of our planet. The authors find that the state of Russian research in this sphere does not match the level of advanced scientific powers.

Stratospheric aerosol geoengineering
AIP Conference Proceedings, 2014In response to global warming, one suggested geoengineering response involves creating a cloud of particles in the stratosphere to reflect some sunlight and cool Earth. While volcanic eruptions show that stratospheric aerosols cool the planet, the volcano analog also warns against geoengineering because of responses such as ozone depletion, regional ...

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.

Abstract The international effort to protect the stratospheric ozone layer successfully integrated science and technology into international environmental diplomacy and solved a global environmental problem. Research scientists identified the problem and its cause, winning a Nobel Prize for their efforts.
