OCO-2 V7


Data Holdings


  • Known data Issues
  • The v7 is a forward processing data stream, and the calibration terms (gain coefficients, temperature dependence, dark subtraction) are estimated from past data. In the reprocessing collection (V7r), the calibration data is estimated from the full timeseries of data (before, during, and after the measurements), and is expected to be of slightly higher quality.
  • OCO-2 filenames contain a "ShortBuildID" string indicating the system version which generated the product. Examples are "B7000" and "B7200". Users should be aware that only the leftmost digit is indicative of science algorithm updates. The other digits only indicate changes to the underlying data system. All "B7..." products can be treated the same for science purposes.
