OCO-2 Documentation

Notes:

  1. 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.
  2. We are adding new documentation here as it becomes available from the OCO-2 Project.

Level 0 and Level 1 Documents

Level 0 Attitude

Level 0 Software Interface Specification; contains description of the Attitude data files. 12/19/2014
Level 0 Ephemeris Level 0 Software Interface Specification; contains description of the Ephemeris data files. 12/19/2014
Level 1A SIS The Level 1A Software Interface Specification (SIS) contains numeration and brief description of all data objects in the Level 1A Sample and Pixel files. It is basically a file description.  2/22/2016
Level 1B SIS The Level 1B Software Interface Specification contains mostly numeration and brief description of all data objects in the Level 1B files. It is a file description. 3/17/2015
Level 1B ATBD This Algorithm Theoretical Basis Document (ATBD) describes the Level 1B data and the process used to transform the inherent instrument measurements (L1A data) into radiometrically calibrated spectra (L1B data). A brief instrument description is included. 7/16/2015

L1B ASD

L1B Algorithm Specification Document (ASD) is a companion document to the L1B ATBD.

Level 2 Documents 

Level 2 Full Physics Retrieval ATBD The algorithm theoretical basis used to retrieve the column-averaged CO2 dry air mole fraction XCO2 and other quantities included in the Level 2 (L2) Product from the spectra collected by the Orbiting Carbon Observatory-2 (OCO-2). It identifies sources of input data; describes the physical theory and mathematical background underlying the use of this information in the retrievals; includes implementation details; and summarizes the assumptions and limitations of the adopted approach.  4/02/2014

Level 2 SIS

Software Interface Specification (SIS) containing numeration and brief description of all data objects. It is a technical file description.  7/15/2015
IMAP-DOAS ATBD The algorithm theoretical basis for the IMAP-DOAS preprocessor, which is used for both screening of the official XCO2 product as well as for the retrieval of Solar-Induced Fluorescence from the 0.76 µm O2 A-band. The IMAP-DOAS preprocessor, just as the ABO2 cloud screen, is implemented in the operational OCO-2 processing pipeline.  6/5/2014
IMAP-DOAS SIS
Software Interface Specification containing numeration and brief description of all data objects. It is a technical file description.  3/17/2015
Level 2 Diagnostic SIS
 Software Interface Specification containing numeration and brief description of all data objects. It is a technical file description.  7/15/2015
ABO2 Details the so-called Oxygen-A Band cloud screening algorithm, which will be one of two primary cloud screening tools implemented in the operational OCO-2 processing pipeline. 9/02/2014
Lite Files, Warn Level and Bias Correction This document provides the details of the contents of the most recent releases of the OCO-2 lite files, the bias correction, and the recommended warn levels.
 
8/31/2015
SIF Lite Files User Guide This document provides details about the Solar Induced Chlorophyll Fluorescence (SIF) Lite files and the SIF correction procedure. 9/1/2015
