AB: Predicting the future atmosphere and its sensitivity to perturbations is a grand challenge for atmospheric scientists. One focus over the past several decades has been the response of stratospheric ozone to variations in solar-ultraviolet radiation, volcanic aerosols, the exhaust of a possible fleet of supersonic aircraft, and changes in the atmospheric burden of man-made chlorofluorcarbons. The interplay between atmospheric models and stratospheric observations of constituents, especially from aircraft campaigns and the Upper Atmosphere Research Satellite, has led to an improved physical basis for the construction of models and more certainty in the predictions of future ozone evolution. Aura, the Earth Observing System platform focused on constituent observations, is providing new information to evaluate and improve models, especially in the lowermost stratosphere and upper troposphere. This talk will highlight comparisons of observations from Aura and other platforms with simulations from several three-dimensional models, emphasizing uncertainties in the simulations that are revealed by comparisons with observations and their relationship to uncertainty in prediction.
