Summary

GEOS-Chem ADJOINT v7 is an adjoint model for Harvard's (GEOS-Chem) modeling system. With the development of this adjoint model, GEOS-Chem is now capable of performing sensitivity analyses, 3D-Var and 4D-Var data assimilation. A detailed description on how to install the package and perform these tests, are provided in the user's manual available for download. Benchmark results have also been included in the manual.

GEOS-Chem ADJOINT v7 was developed with support from NASA JPL through the ROSES AIST 2005 project managed by Dr. Meemong Lee.
