The detection problem can be viewed in terms of the concept of the signal-to-noise ratio, i.e. one can claim to have detected a change in climate once the signal (e.g. the increasing temperature) has risen appreciably above the background noise level (e.g. natural variability of temperature). 4, record 6, English, - signal%2Dto%2Dnoise%20ratio

Signal-to-noise ratio. ... 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. 5, record 6, English, - signal%2Dto%2Dnoise%20ratio

WIND (Wind INfrared Doppler lidar) a pour but de déterminer la vitesse d'aérosol a basse altitude (1 à 10 km) à partir d'un lidar embarqué. [...] La contribution de l'équipe a été de proposer des algorithmes robustes de détection et d'estimation de la fréquence Doppler. Compte tenu du rapport signal à bruit (RSB) «important», supérieur à -5 dB, une modélisation approximative (notch filter) du signal lidar suffit pour obtenir des résultats satisfaisants.

Théorie de la détection du signal : dans cette théorie, on décrit le «signal» (stimulus à identifier ou souvenir à reconnaître) comme une distribution statistique sur un ensemble de valeurs d'abscisse, et le «bruit» (autres stimulations ou autres souvenirs) de la même façon; ce sont les relations entre ces distributions, et les critères de décision adoptés par le sujet, qui gouvernent la détection. 2, record 6, French, - rapport%20signal%20%C3%A0%20bruit

Cette théorie qui connaît différentes applications, en radiotélécommunication notamment mais aussi en sismologie, est également utilisée en climatologie; chacune de ces sciences a établi des critères précis afin de l'utiliser à ses propres fins. Le climat subit des variations qui répondent à des cycles connus et que la statistique permet de distinguer; les climatologues croient que ces bruits, les variations naturelles, s'ils sont d'abord identifiés permettront ensuite de laisser voir le véritable signal confirmant que l'effet de serre anthropique est bien en cours. 3, record 6, French, - rapport%20signal%20%C3%A0%20bruit
