OCO-2 Gridded Bias-Corrected XCO2 Daily Aggregates

Gridded carbon dioxide mole fraction (XCO2) data is produced by applying local kriging to daily aggregates from the Orbiting Carbon Observatory-2 (OCO-2) satellite. The dataset includes other select atmospheric variables derived from bias-corrected OCO-2 measurements. This collection represents the latest version, with previous versions no longer available.

Use Cases

• Mapping global atmospheric carbon dioxide concentrations based on satellite-derived XCO2.
• Analyzing temporal trends in greenhouse gases using daily aggregated time-series data.
• Validating and calibrating carbon flux models with bias-corrected observational data.
• Assimilating gridded XCO2 fields into climate and Earth system models.

Strengths

• Data is produced by NASA, an authoritative source for Earth science observations.
• The dataset is a processed, gridded product (Level 4), which likely simplifies analysis compared to raw satellite data.
• It is the latest version of a maintained collection, suggesting ongoing updates and version control.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided in any source.
• There is a conflict in reported last-updated dates between platforms (2026 vs. 2022), creating uncertainty about data freshness.
• The license is ambiguously listed as 'other-license-specified' without details, which may restrict use.
