The oxygen sensor(also known as an O2 sensor, lambda sensor, or EGO sensor) is one of the most critical sensors on a fuel-injected engine. It resembles a spark plug and is located in the exhaust manifold between the turbo and catalytic converter. When at operating temperature it becomes a miniature battery which generates a voltage based on the differential between the oxygen content of the exhaust gas and the oxygen content of the ambient air. By this method it measures the amount of oxygen in the exhaust stream, allowing the ECM to compensate to some degree for various fuel grades, engine wear, altitude changes, usage of oxygenated fuel, and more. Another big benefit is the ability to keep emissions of carbon monoxide, oxides of nitrogen, and unburned hydrocarbons as low as possible. 3, record 1, English, - oxygen%20sensor

La consommation de carburant et l'émission de gaz polluants peut être drastiquement réduite en ajustant aussi précisément que possible le mélange air/essence qui alimente le moteur. Le dosage optimum (14.7 kg d'air pour 1 kg de carburant) correspond à l'indice 1 d'un coefficient arbitrairement choisi, appelé Lambda; ce mélange est aussi appelé stœchiométrique. Afin de mesurer précisément ce dosage, un capteur d'oxygène est placé en sortie de moteur, avant le catalyseur. Ce capteur est relié au calculateur (ECU), et renseigne en permanence ce dernier sur la proportion de dioxygène (O2) à l'issue de la combustion du mélange air/essence. Si le mélange est pauvre, le dioxygène est en excès et vis versa. 3, record 1, French, - sonde%20d%27oxyg%C3%A8ne%20des%20gaz%20d%27%C3%A9chappement

Even the seemingly small level of disagreement between surface and deep layer temperature trends can not be reproduced by current GCMís, which slave globally-averaged deep tropospheric temperatures to any surface temperature fluctuations... However, we know that convective air currents and the air-conditioning effects of water cause the atmospheric temperature profile to change by a much larger amount, about 80 deg. C, between the surface and 10 km altitude when compared to a hypothetical Earth without these processes... Thus, it is critical to validate whether the parameterizations of moist convective processes in GCMís are realistic enough to capture the ways in which the tropospheric temperature profile fluctuates naturally in response to this transport of heat from the surface to the upper troposphere. 1, record 4, English, - tropospheric%20temperature%20profile

La recherche sur l'ionosphère est importante non seulement pour comprendre la physique de la haute atmosphère, mais aussi pour la propagation radio dans l'ionosphère. C'est pourquoi il a été mis en place en Indonésie un réseau de sondage ionosphérique qui comprend six ionosondes numériques. Les données fournies chaque minute par ces ionosondes, sous forme d'ionogrammes numériques à haute résolution temporelle, seront disponibles. Ces ionogrammes à haute résolution fourniront des renseignements utiles sur les processus et les irrégularités ionosphériques ainsi que pour les radiocommunications à haute fréquence (HF). Des observations par sondages ionosphériques verticaux couvrant un cycle solaire permettront d'élaborer un modèle de prévision pour les radiocommunications à haute fréquence. Grâce à la collaboration entre l'Australie et l'Indonésie, l'exactitude des prévisions de fréquences a pu être améliorée grâce à la gestion en temps réel des fréquences. Cette activité est appuyée par un système de sondage oblique. 1, record 6, French, - sondage%20ionosph%C3%A9rique%20vertical

Historiquement, l'ionosphère a donc été divisée en couches distinctes, la première à avoir été détectée étant la région E (couche de Kennelly-Heaviside). Par ordre alphabétique, on a ensuite la couche F située au-dessus de la couche E. La couche F se subdivise généralement en deux couches, la couche F1 située vers 170 km et la couche F2 située au-delà de 250 km. La couche D, située entre 60 et 90 km échappe au sondage vertical (méthode des échos).
