However, in the tropics, where a few centimeters of uncertainty in sea level can result in large errors in velocity, accuracy is a problem. The ARAMIS program (Altimetrie sur un Rail Atlantique et Mesures in Situ) surveyed temperature and salinity structures in the tropical Atlantic Ocean. In this work, in situ measurements are compared to Jason-1 and -2 data from 2008 in order to check the reliability of inferring tropical Atlantic Ocean dynamics from both data sets, and to validate Jason-2. specialized Altimetry tropics Atlantic OCEAN ATLANTIQUE 030 126 020 34 3-4 319-339 2011 0149-0419 https://www.documentation.ird.fr/hor/fdi:010054246 10.1080/01490419.2011.584833 0149-0419 [F B010054246] https://www.documentation.ird.fr/hor/fdi:010054246 https://www.documentation.ird.fr/intranet/publi/2011/12/010054246.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-01-10 2017-08-23 fdi:010054246 fre
