first detection

The term 'first detection' as it applies to the area of carbon dioxide can be defined as ' Identification of a precursor signal, detectable above the noise of natural climate variation, of a significant change in a climate parameter and attribution of this change to an increase in atmospheric carbon dioxide concentration. The signal may be estimated by numeric modeling of the climate, and the noise can be estimated using instrumental data. For any modeled signal that is estimated, the corresponding noise can be estimated from observational data, and a signal-to-noise ratio can be calculated to provide a quantitative measure of detectability'.
