MOP02N_109: Satellite-Derived Carbon Monoxide Profiles and Totals

MOP02N_109 is a beta satellite data product from the MOPITT instrument on NASA's Terra spacecraft, providing geolocated carbon monoxide profiles and total column amounts. The dataset includes ancillary surface property and cloud condition data, with each retrieval accompanied by an estimated error. Version 109 is an unvalidated beta product subject to recalibration, with data collection ongoing since the instrument's launch on December 18, 1999.

Use Cases

• Tracking global carbon monoxide pollution sources and transport based on retrieved profile and total column data.
• Validating atmospheric chemistry and transport models using satellite-derived CO concentrations and error estimates.
• Analyzing correlations between surface properties/cloud conditions and atmospheric CO levels using the included ancillary data.
• Studying long-term trends in tropospheric pollution from a continuous dataset initiated in 1999.

Strengths

• Provides long-term, continuous global coverage from a satellite instrument launched in 1999.
• Includes estimated error for each carbon monoxide retrieval, supporting uncertainty-aware analysis.
• Contains both vertical profile and total column amount data for carbon monoxide.

Limitations

• The product is explicitly labeled as an unvalidated beta version subject to recalibration, limiting its use for definitive conclusions.
• Key metadata such as row count, column names, and exact file sizes are not provided across any source.
• There is a conflict in the reported 'last updated' date between sources (2025-02-01 vs. 2026-04-10).
