The OCO-2 algorithm theoretical document describes the algorithms in the RT Retrieval Framework used to retrieve the column-averaged CO2 dry air mole fraction XCO2 and other quantities included in the Level 2 (L2) Product from the spectra collected by the Orbiting Carbon Observatory-2 (OCO-2). It identifies sources of input data, describes the physical theory and mathematical background underlying the use of this information in the retrievals; includes implementation details; and summarizes the assumptions and limitations of the adopted approach.
Doxygen documentation can be created from the build directory:
$ make doc
The resulting documentation will be available in the doc/api/html and doc/fortran/html subdirectories.
