warn_icon.gif IMPORTANT MESSAGE Sep 23, 2016    OCO-2 Post-anomaly Data Status   

The OCO-2 instrument experienced an anomaly that interrupted routine operations at 4:28 UTC on August 10, 2016 (Orbit 11212). The cause of the anomaly was resolved, and the instrument recovery process was initiated on August 14 by conducting a standard, week-long decontamination cycle.  The decontamination cycle was completed, and the instrument’s optical bench and detectors were at their nominal operating temperatures on 21 August (Orbit 11376). An initial analysis of the data indicated that, while the instrument was working nominally for science observations, its on-board calibration mechanism had not initialized properly, and was out of alignment, precluding the routine production and delivery of calibrated science data products.  The calibrator alignment issue was diagnosed and resolved on 20:34 UTC on September 15, 2016.  After validating the quality of the data, the standard version 7 (v7) forward streams for L1B and L2 data were reinitiated on September 20, 2016 (Orbit 11815). 

There will be a permanent data gap from August 10 (Orbit 11212) to August 21 (Orbit 11376) because no science observations were collected during that period.  The L1B and L2 science data collected between August 21 and September 20, while the calibrator was not aligned properly, will not be processed as part of the forward v7 data stream, but will be processed as part of the August and September retrospective products (v7r).  These data will be processed using a non-standard calibration product. Users should report any issues that they encounter with these data.

  • As of present, the ATDD at GES DISC is subsettingoperationally certain MODIS/Aqua Radiances and Atmospheres data alongCloudSat and MLS/Aura ground track.  (Skip down to the full list)
  • There are separateCloudSat-, and MLS/Aura-collocated subsets of MODIS/Aqua data.
  • The CloudSat-collocated MODIS/Aqua subsets are provided in two flavors: narrow and wide swaths, correspondingly of about +-5 km and +-100 km along CloudSat track.  Subset are the geolocations,the 1-km and the 250-m MODIS/Aqua Level 1B calibrated radiances, and Atmospheres Level 2 products: Aerosols, Water Vapor, Clouds, Profiles, and the CLoud Mask.
  • The MLS-collocated MODIS/Aqua subsets are only +-100 km.  Calibrated radiances are not subset.  Subset are Geolocations,and the MODIS/Aqua Atmospheres products listed above.

 

  • Naming Convention
    • The CloudSat-collocated MODIS/Aqua subsets are prefixed with "MAC" , and then cary the familiar characters from MODIS/Aqua.  "S0" and "S1" denote the narrow and the wide swath subsets, correspondingly.
    • The MLS-collocated MODIS/Aqua subsets are prefixed with "MAM" , and then cary the familiar characters from MODIS/Aqua.
    • The Data Type Short Name from the table below appears as prefix to the corresponding file.
