Measuring global atmospheric CO2

This image shows averaged atmospheric carbon dioxide between Oct. 1 and Nov. 11, 2014, and is the first global map from NASA's Orbiting Carbon Observatory-2 (OCO-2). Red and orange colors indicate higher carbon dioxide concentrations. Image: NASA/JPL-Caltech.

The OCO-2 mission

NASA's OCO-2 satellite launched on July 2, 2014, to collect measurements of atmospheric carbon dioxide with the precision, resolution, and coverage necessary to characterize the sources and sinks of carbon dioxide and quantify the variability of carbon dioxide over seasonal cycles.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
