TOMSN7L3mtoz: Monthly Global Total Ozone Grid

Monthly averaged total column ozone values from the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) Version 8 instrument. The data are mapped to a global grid of 180 x 288 cells with a lat-long resolution of 1.00 x 1.25 degrees and stored in ASCII format. The dataset was produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center.

Use Cases

• Monitoring global ozone layer health based on satellite-derived total column ozone values.
• Analyzing spatial patterns of ozone concentration across the 1.00 x 1.25 degree global grid.
• Investigating long-term trends in atmospheric ozone using monthly averaged time-series data.
• Validating atmospheric chemistry models with satellite remote sensing observations.

Strengths

• Provides a consistent global spatial grid of 180 x 288 cells for comparative analysis.
• Data originates from a NASA satellite instrument and is produced by an authoritative laboratory (NASA Goddard Space Flight Center Code 614).

Limitations

• Column names and exact data structure are unknown, limiting detailed understanding.
• Sources conflict on the last update date (1993-04-30 vs. 2026-04-09), casting doubt on metadata freshness.
• The dataset size and row count are unspecified across all platforms.
