NASA's Jet Propulsion Laboratory and NASA Earthdata have released the newest version of Orbiting Carbon Observatory-2 (OCO-2) Level 2 (L2) daily data products. These products consist of bias-corrected and filtered XCO2 data. XCO2 is the column-averaged dry-air mole fraction of CO2 in the atmosphere.
The main motivation for this update was to account for a bias in the XCO2 data created by ice buildup on the OCO-2 focal plane arrays. This new version of the L2 daily data products corrects this bias for the data beginning on January 1, 2024. This is true for both the retrospective data product (OCO2_L2_Lite_FP, v11.3r) and the forward stream (OCO2_L2_Fwd_FP, v11.3).
The OCO-2 L2 daily data product landing pages provide additional information and documentation, and these products can be found by using the following OCO-2 keyword search.
The OCO-2/OCO-3 Data User’s Guide provides further information on the instrument, data products and file formats. The latest documentation for the OCO-2 and OCO-3 data products contains user guides and links to additional information regarding the OCO-2/OCO-3 collections.
The OCO-2 satellite was launched on July 2, 2014, and commenced scientific operations on September 6, 2014. More information on the OCO-2 mission, including recent events and science publications, can be found on the mission website.
