In December of 1994, the Tropical Atmosphere Ocean (TAO) Array was completed. The TAO Array is a series of about seventy buoys carefully placed in the tropical Pacific Ocean. Each buoy has special equipment that records information about the water and the air above the water. All of the buoys work together, forming an array, to give scientists a big picture of climate conditions in the area. The buoys send their data to scientists everyday by way of weather satellites that orbit Earth. Since 1994, scientists have been able to watch the water and the air for signs of El Niño. Once they notice that the water is getting warmer, they can keep track of the other changes and help to make predictions about the effects of El Niño better than they ever have before. 1, record 2, English, - Tropical%20Atmosphere%20Ocean%20Array

En janvier 1985, sous les auspices du CIUS, de l'OMM et de la Commission océanographique intergouvernementale(COI) de l'UNESCO, le Programme TOGA sur les océans tropicaux et l'atmosphère globale réunissant les représentants de 18 nations s’est lancé dans un projet décennal d’observations. Au cœur du projet figurait l'amarrage de quelque 70 bouées fixes constituant le Réseau océan-atmosphère pour l'observation dans les mers tropicales(TAO)-disséminées dans le Pacifique équatorial. Ces bouées envoient en permanence par satellite des relevés en temps réel concernant la température des eaux à la surface, la force des vents de surface et le taux de salinité aux centres de recherche qui les utilisent, pour élaborer des modèles climatiques aux fins des prévisions météorologiques. Ces données TAO sont complétées par le parachutage de bouées dérivantes non récupérables, les mesures altimétriques par radar du satellite franco-américain Topex/Poséidon et les relevés des températures des eaux de surface obtenus par satellite grâce à des capteurs thermosensibles à infrarouges. 1, record 2, French, - R%C3%A9seau%20oc%C3%A9an%2Datmosph%C3%A8re%20pour%20observation%20dans%20les%20mers%20tropicales
