ML3DBOH: Daily Binned Hydroxyl Mixing Ratio from Aura Satellite, 2004-2014

Continuous data from August 2, 2004 to December 12, 2009, with intermittent collection in subsequent years. The dataset contains daily binned hydroxyl (OH) mixing ratios measured by the Microwave Limb Sounder (MLS) on NASA's Aura satellite, archived in netCDF4 format. Spatial coverage is near-global (-82 to +82 degrees latitude) with a 4° by 5° resolution.

Use Cases

• Modeling hydroxyl radical distribution and its role in atmospheric chemistry based on near-global satellite measurements.
• Analyzing long-term trends in upper atmospheric composition based on the continuous 2004-2009 time series.
• Validating climate and chemistry models based on the vertical profile data from 31.6 to 0.00316 hPa.
• Studying spatial patterns of short-lived chemical species based on the 4° latitude by 5° longitude binned grid.

Strengths

• Continuous temporal coverage from August 2004 to December 2009.
• Near-global spatial coverage from -82 to +82 degrees latitude.
• Data is archived in the interoperable netCDF4 format, compatible with HDF5 tools.
• Provides a defined useful vertical range from 31.6 to 0.00316 hPa with ~3 km vertical resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Primary data collection ended in 2009, with only brief 30-day campaigns in later years.
• Row count is unknown, which may limit suitability assessment for specific ML tasks.
