OCO-2 public products now available!
Please visit GES DISC for all OCO-2 data products and please also visit our CO2 portal link below.
These data have been produced by the OCO-2 project, and are provided freely to the public. In order to improve our product and have continued support for this work, we need user feedback and user acknowledgement of data usage. Therefore, we request that when publishing using OCO-2 data, please acknowledge NASA and the OCO-2 project.
- Include OCO-2 as a keyword to facilitate subsequent searches of bibliographic databases if it is a significant part of the publication
- Include a bibliographic citation for OCO-2 data. The most relevant citations currently are Wunch et al. [2011a and 2011b], O’Dell et al. , Crisp et al. , and Frankenberg et al. [2014a and 2014b]
- Include the following acknowledgements: “These data were produced by the OCO-2 project at the Jet Propulsion Laboratory, California Institute of Technology, and obtained from the OCO-2 data archive maintained at the NASA Goddard Earth Science Data and Information Services Center.”
- We recommend sending courtesy copies of publications to the OCO-2 Project Scientist, Michael.R.Gunson@jpl.nasa.gov, and Deputy Project Scientist, Annmarie.Eldering@jpl.nasa.gov

An exciting week for us – Sept 6th, 2015 marks one year of operational data collection for OCO-2!
And, we have prepared the year of OCO-2 lite files, with bias correction and warn levels! We will open the portal on Tuesday (9/8/2015) CO2 Data Portal. to share those datasets. There is one file per day (much fewer than the standard product), and the number of ancillary data fields are reduced to create smaller files. Documentation will also be on the portal.
Key information in the documentation:
- Descriptions of the data fields and organization in the netcdf files.
- For XCO2, we describe in detail the warn levels, which are an indication of the data quality. The user can trade off data quality and data volume by selection of warn levels. See attached for details.
- Also for XCO2, we describe the process used to calculate the bias correction, and provide characteristics of the corrections that were applied. The uncorrected XCO2 and fields used in the correction are all included in the netcdf files.
- The SIF lite file document describes the data fields and corrections that are applied to that product.
As with the L2Std and L2Dia files, there is a collection for the forward processing stream (v7) and the reprocessing stream (v7r), which runs from Sept 2014 through May 2015. The reprocessing data stream has a larger data volume.
