ML3DZMBRO: Daily Zonal Mean Bromine Monoxide Measurements from Aura MLS Satellite

Near-global (-85° to 85° latitude) daily zonal mean measurements of bromine monoxide (BrO) from the EOS Aura Microwave Limb Sounder satellite. The data version is 5.0, with coverage from August 2, 2005 to present, spaced every 10 degrees in latitude. This product is produced by the National Aeronautics and Space Administration (NASA) and stored in netCDF4 files following Climate and Forecast metadata conventions.

Use Cases

• Modeling stratospheric ozone depletion based on bromine monoxide concentrations.
• Analyzing long-term trends in atmospheric bromine compounds based on the data's temporal coverage from 2005 onward.
• Studying latitudinal distribution of BrO based on the 10-degree zonal mean spatial structure.
• Validating atmospheric chemistry models using the precision (error) estimates provided for each latitude band and pressure level.

Strengths

• Long-term temporal coverage from August 2, 2005 to current.
• Near-global spatial coverage from -85 to 85 degrees latitude.
• Data follows standardized Climate and Forecast (CF) metadata conventions in netCDF4 format.
• Provides average, error (precision), solar zenith angle, and local solar time for each latitude band and pressure level.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
