The Goddard Earth Observing System Model, Version 5 (GEOS-5) is a system of models integrated using the Earth System Modeling Framework (ESMF). The GEOS-5 Data Assimilation System (GEOS-5 DAS) integrates the GEOS-5 Atmospheric Global Climate Model (GEOS-5 GCM) with the Gridpoint Statistical Interpolation (GSI) atmospheric analysis developed jointly with NOAA/NCEP/EMC. The GEOS-5 systems are being developed in the GMAO to support NASA's earth science research in data analysis, observing system modeling and design, climate and weather prediction, and basic research.
GEOS-5 is supported by NASA's Modeling Analysis and Prediction (MAP) Program.

GEOS-5 4DVAR ADAS: Four-dimensional Variational Data Assimilation System
The GMAO atmospheric data assimilation system is a three-dimensional variational 3DVAR system that combines the GMAO atmospheric general circulation model [AGCM] with the jointly-developed GMAO/NCEP Grid-point Statistical Interpolation GSI analysis. To make better use of satellite observations the GMAO has extended its 3DVAR to implement an atmospheric four-dimensional variational (4DVAR) system that adds the forward model as a constraint to the analysis minimization problem. The 4DVAR extension of the GEOS-5 ADAS brings in the tangent linear and adjoint models of the GEOS-5 finite-volume hydrodynamics with simplified linearized physics and various upgrades to GSI.
