warn_icon.gif IMPORTANT MESSAGE Sep 23, 2016    OCO-2 Resumes Data Delivery   

OCO-2 Project resumed delivery of calibrated radiances and science retrievals data for archive and distribution at GES DISC, starting with Data Day September 20, 2016. After experiencing anomaly on August 10, and  re-powering on August 14, the instrument had to go through a lengthy decontamination and calibration cycle.  There will exist permanent gap in science data between August 11-20, 2016. Users should be aware that data in the following period, August 21 - September 15, 2016, will be retrospectively processed into version 7r, but it were collected while the calibrator door position was offset.

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.
