ML3DBCO: Daily Binned Carbon Monoxide Mixing Ratios from Aura Satellite

MLS/Aura Level 3 Daily Binned Carbon Monoxide (CO) Mixing Ratio on Assorted Grids V005 (ML3DBCO) is a NASA dataset providing daily binned carbon monoxide measurements from the Microwave Limb Sounder instrument on the Aura satellite. Data coverage spans from August 2, 2005 to the present, with near-global spatial coverage from -82 to +82 degrees latitude. The data is archived in netCDF4 format, with each file containing multiple group objects for different vertical grids and statistical summaries.

Use Cases

• Modeling global carbon monoxide distribution based on daily binned, near-global measurements.
• Analyzing long-term trends in atmospheric pollution based on data spanning from 2005 to present.
• Studying vertical profiles of trace gases based on data binned on various pressure and potential temperature grids.
• Conducting spatial analysis of atmospheric constituents based on the 4x5 degree latitude-longitude grid.

Strengths

• Long-term temporal coverage from August 2005 to current.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Data is structured in netCDF4 format with multiple statistical groups (average, min, max, std dev, rms).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
