CRU Information Sheet no. 13: Volcanoes and their effect on climate
Laki volcano in Iceland. Ironically, most of the ejected material from this eruption remained in the lower parts of the atmosphere, so Franklin had the right idea but the wrong volcano. Figure 1 ... volcanic event. Earlier work, from the 1960s onwards, suggested that when eruption clouds reach the lower stratosphere (about 20-25km aloft) the dust spreads around over subsequent months forming a veil ...

Ozone Chemistry
These inactive compounds, for example ClONO2, are collectively ... compounds, including HCFC's, can also convert active chlorine to HCl. In the troposphere and lower stratosphere NO, NO2 and OH radicles are catalysts in ozone degredation. But they are equally ...

Science - Ozone Depletion
CFCs are mixed worldwide by the large-scale motions of the atmosphere and survive until, after ... (O3) varies with height in the atmosphere. Note that most of the ozone is in the lower stratosphere. The "ozone layer" resides at an altitude of about 12 to 15 miles (20 to 25 ...

Science - The Antarctic Ozone Hole
Although increasing greenhouse gas concentrations in the atmosphere may result in warmer surface temperatures, colder temperatures are expected to occur in the stratosphere. In fact, temperatures in the lower stratosphere, as measured by NOAA's Microwave Sounding Unit, have cooled during the past 22-years, the length of the satellite record. Colder stratospheric temperatures ...

1-9 Ozone Reactions: Physics and Chemistry of the Stratosphere
Unit Problem to Ponder: If we have too much ozone in the troposphere in large cities and too little in the stratosphere, why can't we just pipe it up from the cities to the lower stratosphere (the level where jet aircraft fly)? Unit exam questions from previous years Unit discussions from previous years, available from the current online ...

Climate Prediction Center - Stratosphere: Winter Bulletins
Northern Hemisphere. The positive anomalies in total ozone were associated with the meteorological conditions of positive anomalies of lower stratosphere temperature. Arctic temperatures were not sufficiently low for the formation of polar stratospheric clouds and consequent chemical ozone depletion within the polar vortex. Chlorine and other ...
