The graphics present the monthly and annual departure between the observed ozone values at each station and the pre-1980 climatology. Missing months are depicted with the letter "M". Monthly data may be missing for various reasons (tranmission and instrument problems, low sun angles, cloudy conditions, insufficient number of observations, etc).
