About The Cover

Cover image expansion

COVER This artist's rendition of Earth uses data obtained from the Orbiting Carbon Observatory-2 (OCO-2) to show a time-averaged, false-color view of the concentration of atmospheric CO2 over Asia, parts of Africa, and Europe. In this issue (see page 186), the initial results from the OCO-2 mission are reported, including El Niño's effects on CO2 fluxes, detection of CO2 emissions from point sources, and measurement of terrestrial photosynthesis.
