TOMSEPL3zaer: Daily UV Aerosol Index Zonal Means

UV aerosol index values are averaged in 5-degree latitude bands. This Earth Probe Total Ozone Mapping Spectrometer (TOMS) version 8 product provides daily and monthly zonal means for atmospheric aerosol monitoring. The data were produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center and are stored in an ASCII format.

Use Cases

• Tracking long-range aerosol transport patterns based on daily zonal means.
• Analyzing latitudinal distribution of aerosols using 5-degree band averages.
• Validating atmospheric chemistry and climate models with satellite-derived UV aerosol index data.

Strengths

• Produced by a definitive source: NASA Goddard Space Flight Center's Laboratory for Atmospheres.
• Data is spatially aggregated into consistent 5-degree latitude zonal means.

Limitations

• Metadata completeness is low: column names, row counts, and file sizes are unknown across all sources.
• Conflicting freshness: update dates range from 2005 to a future date in 2026, indicating potential metadata errors.
