MOPITT: Daily Gridded Carbon Monoxide Measurements from Satellite, 1999-2020

MOPITT CO gridded daily means version 9 data product contains daily mean-gridded versions of Level 2 CO profile and total column retrievals, including averaging kernels. The instrument was launched aboard NASA's Terra spacecraft on December 18, 1999, and data collection for this product was completed in March of 2020. It was constructed by a Canadian consortium funded by the Canadian Space Agency.

Use Cases

• Modeling global tropospheric carbon monoxide transport based on daily gridded retrievals.
• Analyzing long-term trends in atmospheric pollution based on data spanning from 1999 to 2020.
• Validating atmospheric chemistry models based on satellite-derived CO profiles and total columns.
• Studying the impact of averaging kernels on retrieval quality for inverse modeling.

Strengths

• Data collection spans over 20 years, from December 1999 to March 2020.
• Includes gridded averaging kernels, which are critical for proper use of the retrievals.
• Product is version 9, suggesting multiple iterations of processing and refinement.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection ended in 2020, limiting analysis of recent trends.
