FLDAS: système d'assimilation des données sur la terre du réseau de systèmes d'alerte précoce contre la famine (FEWS NET)
L'ensemble de données FLDAS (McNally et al., 2017) a été conçu pour faciliter les évaluations de la sécurité alimentaire dans les pays en développement où les données sont rares. Il inclut des informations sur de nombreuses variables liées au climat, y compris l'humidité, l'évaporation, l'évapotranspiration, la température moyenne du sol, le taux total de précipitations, etc. Il existe plusieurs ensembles de données FLDAS : … climat cryosphère évaporation humidité ldas mensuel -
GLDAS-2.1: Global Land Data Assimilation System
La version 2 du système d'assimilation des données terrestres (GLDAS-2) de la NASA comprend trois composants: GLDAS-2.0, GLDAS-2.1 et GLDAS-2.2. GLDAS-2.0 est entièrement forcé par les données d'entrée de forçage météorologique de Princeton et fournit une série temporelle cohérente de 1948 à 2014.

NLDAS-2: North American Land Data Assimilation System Forcing Fields
Le système d'assimilation des données terrestres (LDAS) combine plusieurs sources d'observations (telles que les données de pluviomètre, les données satellitaires et les mesures de précipitations par radar) pour produire des estimations des propriétés climatologiques à la surface de la Terre ou à proximité. Cet ensemble de données est le fichier de forçage principal (par défaut) (fichier A) pour la phase … climat évaporation forçage geophysical par heure humidité -
