Discusses simultaneous measurements of stratospheric chlorine nitrate and nitric acid as they deplete the ozone in the lower stratosphere over Antarctica. Incidence of polar stratospheric cloud (PSC) formation in the lower stratosphere; Sedimentation of PSC particles in lower Antarctica vortex.
- Effect of ozone depletion on atmospheric CH4 and CO concentrations. Bakki, S.; Law, K.S. // Nature;10/13/1994, Vol. 371 Issue 6498, p595
Reports on the effect of ozone depletion on atmospheric methane and carbon monoxide concentrations. Observation by global surface-based measurements; Two-dimensional model simulations; Low values in stratospheric ozone concentration.
- number cruncher. // Laboratory News;Nov2014, p4
Statistics based on new research are presented suggesting that the ozone hole is shrinking.
- Aspects of stratospheric long-term changes induced by ozone depletion. Cagnazzo, Chiara; Claud, Chantal; Hare, Sylvia // Climate Dynamics;Aug2006, Vol. 27 Issue 1, p101
The effect of the stratospheric ozone depletion on the thermal and dynamical structure of the middle atmosphere is assessed using two 5-member ensembles of transient GCM simulations; one including linear trends in ozone, the other not, for the 1980â€“1999 period. Simulated temperatures and...
- Using 3DVAR data assimilation system to improve ozone simulations in the Mexico City basin. Bei, N.; de Foy, B.; Lei, W.; Zavala, M.; Molina, L. T. // Atmospheric Chemistry & Physics;2008, Vol. 8 Issue 24, p7353
This study investigates the improvement of ozone (O3) simulations in the Mexico City basin using a threedimensional variational (3DVAR) data assimilation system in meteorological simulations during the MCMA-2003 field measurement campaign. Meteorological simulations from the NCAR/Penn State...
- OZONE HOLES: born by stratospheric air flows. Kashkin, V. B.; Khlebopros, R.G. // SCIENCE First Hand;2007, Vol. 13 Issue 1, p48
The article provides information on the significance of the ozone layer to atmospheric changes affecting life on the Earth. Ozone is a specific tri-atomic form of oxygen that comprised one part of atmospheric gases. It reduces the short wavelength portion of ultraviolet radiation. Aside from...
- Ozone Hole Diminishing. // Australasian Science;Nov2007, Vol. 28 Issue 10, p13
The article reports that the Earth's ozone hole has decreased. The size of depleted ozone layer decreased to 25 million square kilometers from 28 million square kilometers. The reduction is attributed to decreased levels of chlorofluorocarbons and other damaging chemicals in the lower...
- Acid rain and ozone depletion from pulsed Siberian Traps magmatism. Black, Benjamin A.; Lamarque, Jean-François; Shields, Christine A.; Elkins-Tanton, Linda T.; Kiehl, Jeffrey T. // Geology;Jan2014, Vol. 42 Issue 1, p67
The Siberian Traps flood basalts have been invoked as a trigger for the catastrophic end-Permian mass extinction. Widespread aberrant plant remains across the Permian-Triassic boundary provide evidence that atmospheric stress contributed to the collapse in terrestrial diversity. We used detailed...
