The detection and attribution of forced changes ( trends ) in the climate system, whether of natural or anthropogenic origin, is a signal-to-noise problem. The challenge comes in defining the signal and in characterizing the noise. In particular, there are various sources of long-term memory which intorduce serial correlations in the noise, and can lead to false apparent trends if they are not accounted for. The issue is particulatrly evident in stratospheric climate and ozone, where the observed record is relatively short (compared with the troposphere) and where scientists have been fooled in the past by apparent trends that subsequently reverse. The purpose of this summer sc hool is to introduce students and post-doctoral researchers in atmospheric science to the statistical tools needed to address these problems, in a language accessible to them. Stratopheric dynamics and ozone will be especially featured in order to illustrate the issues, but the summer school will be of interest to a more general audience.
