TES/Aura L3 Ozone Daily Gridded V006: Global Atmospheric Profiles

Global atmospheric profiles of ozone and temperature are provided from the Tropospheric Emission Spectrometer aboard NASA's Aura satellite. Daily and monthly Level 3 data interpolates Level 2 profiles onto a 2° latitude by 4° longitude grid at standard pressure levels. Separate product files contain volume mixing ratios for atmospheric species and temperature, derived from limb or nadir observation modes.

Use Cases

• Monitoring global ozone distribution based on daily gridded volume mixing ratio data.
• Analyzing atmospheric temperature profiles across pressure levels from nadir and limb observations.
• Studying air quality and atmospheric chemistry using interpolated 3-D gas distribution maps.
• Tracking temporal changes in atmospheric species via daily (approx. 26-hour) and monthly aggregated surveys.

Strengths

• Data originates from a well-defined NASA satellite instrument (TES/Aura) launched on July 15, 2004.
• Provides a 3-D global representation with a defined spatial grid of 2° latitude by 4° longitude.
• Includes data from two distinct observation modes (limb and nadir), offering complementary atmospheric views.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• The 'last updated' metadata field shows a conflict: one source lists 2026-04-09, another lists 2018-01-22.
• Data collection is complete, indicating the dataset is historical with no new observations.

Provenance

Source

NASA Aura satellite Tropospheric Emission Spectrometer (TES) instrument.

Collection Method

Level 2 atmospheric profiles collected in Global Surveys were interpolated onto a uniform global grid by the TES Science Data Processing L3 subsystem.

Time Range

Data collection began after the July 15, 2004 launch and is now complete. Granules cover daily (approx. 26-hour) and monthly periods.
