NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission was motivated by the need to diagnose how the increasing concentration of atmospheric carbon dioxide (CO_2) is altering the productivity of the biosphere and the uptake of CO_2 by the oceans. Launched on 2 July 2014, OCO-2 provides retrievals of the column-averaged CO_2 dry-air mole fraction (XCO_2) as well as the fluorescence from chlorophyll in terrestrial plants. The seasonal pattern of uptake by the terrestrial biosphere is recorded in fluorescence and the drawdown of XCO_2 during summer. Launched just before one of the most intense El Niños of the past century, OCO-2 measurements of XCO_2 and fluorescence record the impact of the large change in ocean temperature and rainfall on uptake and release of CO_2 by the oceans and biosphere.
