TOMSEPL3ztoz: Daily Zonal Ozone Means

Earth Probe Total Ozone Mapping Spectrometer version 8 data provides daily total column ozone values averaged in 5-degree latitude bands. The ASCII-formatted zonal means were produced by NASA Goddard Space Flight Center's Laboratory for Atmospheres. This dataset supports analysis of atmospheric ozone distribution over time.

Use Cases

• Tracking ozone layer depletion trends based on daily total column ozone values.
• Analyzing latitudinal ozone distribution patterns based on 5-degree band averages.
• Validating atmospheric chemistry models using NASA-produced satellite instrument data.
• Studying seasonal ozone variability using the time-series of daily zonal means.

Strengths

• Data originates from a NASA satellite instrument (Earth Probe TOMS) and is produced by a specific NASA laboratory (Code 614).
• Provides spatially aggregated data in a consistent 5-degree latitude band structure.

Limitations

• Column names and exact row counts are unknown across all sources.
• Sources conflict on freshness: one platform shows a 2026 update date, while another shows a 2005 date.
• Documentation details are sparse; specific file formats (BIN, PDF, etc.) are listed but their content is not described.
