ML3DBCLO: Daily Binned Chlorine Monoxide Mixing Ratio from Aura Satellite

EOS Aura Microwave Limb Sounder daily binned chlorine monoxide (ClO) data from August 2, 2005 to present. The dataset provides near-global coverage from -82 to +82 degrees latitude at a 4x5 degree resolution, with a useful vertical range between 147 and 1.0 hPa. Data is archived in netCDF4 format by NASA and includes profiles subdivided by orbit type and solar zenith angle.

Use Cases

• Modeling stratospheric ozone depletion based on chlorine monoxide mixing ratios.
• Analyzing polar vortex dynamics using the 'equivalent latitude' vs 'potential temperature' zonal mean groups.
• Studying diurnal variations in ClO using the daytime (SZA < 90) and nighttime (SZA > 110) profile subdivisions.
• Investigating longitudinal and latitudinal ClO distributions using the lat-lon map vs pressure group data.

Strengths

• Continuous temporal coverage from August 2, 2005 to the present.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Data includes statistical aggregates (average, min, max, std dev, rms) for each profile group.
• Archived in netCDF4 format, compatible with standard HDF5 tools.

Limitations

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