GLDAS-1: Global Land Data Assimilation System (NASA/GLDAS/V001/NOAH/G025/T3H)

Version V001

Global Land Data Assimilation System (GLDAS) ingests satellite and
ground-based observational data products. Using advanced land surface
modeling and data assimilation techniques, it generates optimal
fields of land surface states and fluxes.

GLDAS-1 contains a series of land surface parameters simulated from the
Noah 2.7.1 model in the GLDAS. The data is acquired as part of the mission
of NASA’s Earth Science Division and archived and distributed by the
Goddard Earth Sciences (GES) and Data and Information Services Center(DISC).
