TES/Aura L2 Ozone Lite Nadir V007: Tropospheric Ozone Profiles

Global satellite retrievals provide tropospheric ozone profiles and related atmospheric parameters from the TES instrument on NASA's Aura satellite. Each Level 2 standard product contains retrieved species profiles, estimated errors, geolocation, and quality data for an entire global survey. A global survey consists of observations along 16 consecutive orbits, performing up to 3,200 retrievals per two-day cycle.

Use Cases

• Monitoring global tropospheric ozone concentrations based on retrieved Volume Mixing Ratios (VMR).
• Analyzing vertical resolution and error estimates of atmospheric profiles from the retrieval process.
• Studying surface temperature and atmospheric temperature profiles derived from modeled spectra.
• Tracking changes in observation methodology, such as scan resolution changes after April 24, 2005.
• Conforming data analysis to the HDF-EOS Aura File Format Guidelines used by the swath objects.

Strengths

• Provides up to 3,200 retrievals per two-day global survey cycle.
• Includes detailed diagnostic quantities like precision, total error, vertical resolution, and total column density.
• Data is structured in a standardized swath format conforming to HDF-EOS Aura guidelines.

Limitations

• Column names and exact row counts are not provided in the metadata.
• The last updated date conflicts between sources (2026-04-09 and 2015-12-31).
• The dataset's license is ambiguously listed as 'other-license-specified'.
