Abstract: Significant advances have been made recently both in observational studies and in dynamical numerical simulations of stratosphere warmings. Observed characteristics of warmings are reviewed, with discussion of the trajectory ...

Abstract: The most long-lived satellite set of ozone observations, to date, is that derived from the Backscatter Ultraviolet (BUV) ozone sensor on Nimbus 4 and extends from April 1970 through 1976. Unfortunately, this experiment ...

Abstract: A major question concerning the observed long-term changes of zonal average tow ozone has always been that the spatially limited ground-based ozone sampling sites are susceptible to a sampling problem. That is, the regional ...
