Les données du spectromètre TOMS (Total Ozone Mapping Spectrometer) représentent le principal enregistrement continu à long terme des observations par satellite disponibles pour surveiller les tendances mondiales et régionales de l'ozone total au cours des 25 dernières années. Les données sont produites par le Laboratory for Atmospheres du centre de vol spatial Goddard de la NASA. Les produits de données TOMS de la version 8 incluent des données maillées de niveau 3 (1,0 x 1,25 degrés). L'instrument de surveillance de l'ozone (OMI, Ozone Monitoring Instrument) à bord du satellite Aura (juillet 2004 à aujourd'hui) offre une résolution plus élevée (1,0 x 1,0 degré).
Ces données représentent un produit d'ozone fusionné à partir des données TOMS/EarthProbe, TOMS/Nimbus-7, TOMS/Meteor-3, OMI/Aura et USGS interpolées pour les dates sans données.
La distribution des données du Goddard Earth Sciences Data and Information Services Center (GES DISC) est financée par la Science Mission Directorate (SMD) de la NASA. Conformément à la Politique sur les données et informations scientifiques de la Terre de la NASA, les données de l'archive GES DISC sont disponibles sans frais pour la communauté des utilisateurs.
