ML3DZCO: Daily Binned Carbon Monoxide Mixing Ratios from Aura Satellite

MLS/Aura Level 3 daily binned carbon monoxide (CO) mixing ratio data on zonal and vertical grids. The dataset is produced by NASA and covers from August 2, 2005 to the present. Data is near-global (-82 to +82 degrees latitude) with a vertical range between 215 and 0.00464 hPa.

Use Cases

• Modeling global carbon monoxide transport based on near-global latitude and pressure grid data.
• Analyzing long-term trends in atmospheric chemistry based on data coverage from 2005 to present.
• Studying stratospheric-tropospheric exchange processes based on vertical resolution and pressure range.
• Comparing vortex-averaged atmospheric conditions based on the 'vortex average vs potential temperature' data group.

Strengths

• Long temporal coverage from August 2005 to current, providing over 18 years of data.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Data is archived in netCDF4 format, which is compatible with HDF5 readers and tools.
• Each file contains multiple statistical views (average, min, max, std dev, rms) for analysis.

Limitations

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