The Orbiting Carbon Observatory 2 (OCO-2) is NASA’s first dedicated Earth remote sensing satellite to study atmospheric carbon dioxide from Space. OCO-2 will be collecting space-based global measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks on regional scales. OCO-2 will also be able to quantify CO2 variability over the seasonal cycles year after year.

The observatory took the lead position in the A-Train formation on August 3, 2014.

The Goddard Earth Science Data and Information Services Center (GES DISC), in partnership with the OCO-2 Project, will archive and distribute data from OCO-2. JPL is also providing high quality media on all aspects of the mission.


About the Instrument:

The Orbiting Carbon Observatory-2 (OCO-2) is comprised of a single instrument that flies on a dedicated spacecraft.

The instrument, consisting of three high resolution grating spectrometers, makes coincident measurements of reflected sunlight in the near-infrared CO2 near 1.61 and 2.06 μm and in molecular oxygen (O2) A-Band at 0.76 μm

It will acquire precise measurements of total column atmospheric CO2.
