ML3MBHOCL: Monthly Hypochlorous Acid Measurements from Aura Satellite

Monthly binned data for hypochlorous acid (HOCl) mixing ratios derived from the EOS Aura Microwave Limb Sounder (MLS) 640 GHz radiometer. The dataset provides near-global coverage from -82 to +82 degrees latitude at a 4°x5° resolution, with a useful vertical range from 10 to 2.15 hPa. It is produced by the National Aeronautics and Space Administration and archived in netCDF4 format.

Use Cases

• Modeling stratospheric ozone depletion cycles based on monthly HOCl mixing ratios.
• Analyzing latitudinal and vertical distributions of halogen species based on binned grid data.
• Studying diurnal variations in atmospheric chemistry based on daytime and nighttime profile groups.
• Investigating polar vortex dynamics based on equivalent latitude and vortex average groups.

Strengths

• Data version 4.2 indicates a mature, processed product.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Vertical resolution of about 6 km within the recommended 10 to 2.15 hPa range.
• Includes statistical summaries (average, min, max, std dev, rms) and subsets for ascending/descending orbits and day/night.

Limitations

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