Orbiting Carbon Observatory-2/OCO-2/OCO-2 GEOS Level 3 monthly, 0.5x0.625 assimilated CO2 V10r also referred to as: OCO-2 GEOS Level 3 monthly
NASA
OCO-2 GEOS (Goddard Earth Observing System) Level 3 data are produced by ingesting OCO-2 L2 retrievals every 6 hours with GEOS CoDAS, a modeling and data assimilation system maintained by NASA’s Global Modeling and Assimilation Office (GMAO). GEOS CoDAS uses a high-performance computing implementation of the Gridpoint Statistical Interpolation approach for solving the state estimation problem. GSI finds the analyzed state that minimizes the three-dimensional variational (3D-Var) cost function formulation of the state estimation problem.
