=================== Other Documentation =================== ATBD ==== 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 ======= `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.
