The NASA Orbiting Carbon Observatory (OCO) missions collect space-based measurements needed to quantify variations in the column averaged atmospheric carbon dioxide (CO2) dry air mole fraction, XCO2, with the precision, resolution, and coverage needed to improve our understanding of surface CO2 sources and sinks (fluxes) over different scales and the processes controlling their variability over the seasonal cycle. They do this by producing Level 1B, Level 2, Level 3, and other data products for the research community. The repositories within this organization are related to the OCO missions' data processing and usage.
