MLS/Aura ML2O3: Global Ozone Mixing Ratio Profiles from Satellite

MLS/Aura Level 2 Ozone (O3) Mixing Ratio V005 provides near-global atmospheric ozone profiles measured by the Microwave Limb Sounder instrument. The data version is 5.0, with profiles spaced 1.5 degrees along the orbit track and a useful vertical range from 261 to 0.0215 hPa. This dataset is produced by the National Aeronautics and Space Administration and stored in HDF-EOS5 format.

Use Cases

• Modeling stratospheric ozone depletion based on vertical profile data.
• Analyzing global ozone distribution patterns based on near-global latitude coverage.
• Validating atmospheric chemistry models based on satellite-derived mixing ratios.
• Studying seasonal and long-term ozone trends based on daily orbital data.

Strengths

• Data version 5.0 indicates a mature, processed standard product.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Vertical resolution between 2.5 and 6 km across the profile range.

Limitations

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