Quick Facts

- OCO-3 is a critical element in the continuation of global carbon dioxide (CO2) measurements focused on understanding the regional sources and sinks of CO2.

- OCO-3 can also contribute to focused study of how space based measurements can constrain rapidly changing anthropogenic (man-made) emissions. Anthropogenic emissions could be the largest source of uncertainty in the global carbon budget as OCO-3 measurements reduce uncertainty of natural fluxes.

- OCO-3 measurements can be combined with evapotranspiration and biomass measurements to study process details of the terrestrial ecosystem.

- OCO-2 has demonstrated that atmospheric XCO2 can be measured from space with precision of better than 1 ppm. OCO-3 is expected to have similar performance.
