TeachMeFinance.com - explain Signal-to-Noise Ratio Signal-to-Noise Ratio The term 'Signal-to-Noise Ratio' as it applies to the area of carbon dioxide can be defined as ' A quantitative measure of the statistical detectability of a signal, expressed as a ratio of the magnitude of the signal relative to the variability. For first detection of a CO2-induced climate change, the model signal is the mean change or anomaly in some climatic variable, usually surface air temperature, attributed by a numerical model to increased concentrations of carbon dioxide. Observed noise is the standard deviation or natural variability computed from observations of that variable and adjusted for sample size, autocorrelation, and time averaging'. The term 'Signal-to-Noise Ratio' as it applies to the area of the weather can be defined as ' A ratio that measures the comprehensibility of data, usually expressed as the signal power divided by the noise power, usually expressed in decibels (dB)'.
