TRPSCRCOS6H3D: Carbon Monoxide Atmospheric Uncertainty Analysis

2005-2021 data provides the ensemble spread of carbon monoxide concentrations, a measure of analysis uncertainty from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset is produced using JPL's MOMO-Chem data assimilation framework, which simultaneously optimizes concentrations and emissions from multiple satellite sensors. Data is provided at 6-hourly resolution on a global grid with 27 vertical pressure levels.

Use Cases

• Quantifying uncertainty in atmospheric carbon monoxide analyses for model validation based on the ensemble spread metric.
• Studying long-term trends and variability in tropospheric chemistry from 2005 to 2021.
• Assimilating multi-species chemical observations using the described MOMO-Chem framework for emission inversion studies.
• Analyzing the vertical distribution of trace gases across 27 pressure levels between 1000 and 60 hPa.

Strengths

• Covers a 17-year time range (2005-2021) for longitudinal climate studies.
• Provides high temporal (6-hourly) and spatial (1.125° x 1.125°) resolution for detailed atmospheric analysis.
• Derived from a sophisticated multi-species data assimilation system (MOMO-Chem) that uses multiple satellite sensors.

Limitations

• Specific column names and data volume (size/rows) are not documented in the provided metadata.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
• Data freshness is unclear; the last metadata update is listed as 2026-04-09, which may be a system artifact.
