MOD08_M3 V6.1 est un produit atmosphérique global qui contient des valeurs moyennes mensuelles de 1 x 1 degré pour les paramètres atmosphériques.
Ces paramètres sont liés aux propriétés des particules d'aérosols atmosphériques, à la charge totale d'ozone, à la vapeur d'eau atmosphérique, aux propriétés optiques et physiques des nuages, ainsi qu'aux indices de stabilité atmosphérique. Le produit fournit également des moyennes, des écarts types, des statistiques pondérées par l'assurance qualité, des distributions log-normales, des estimations d'incertitude et des statistiques pour les fractions de pixels qui répondent à une condition donnée. Vous trouverez ci-dessous un sous-ensemble des bandes. Pour obtenir la liste complète, consultez la liste des bandes MOD08.
