TRPSDL2O3AIRSFS: Global Ozone Vertical Profiles from Aqua Satellite

Global vertical profiles of atmospheric ozone (O3) retrieved from the AIRS instrument on NASA's Aqua satellite. Data are provided daily from February 1, 2021, onward, with a spatial resolution of 13.5 km at nadir and reported across 26 vertical levels from the surface to 0.1 hPa. The dataset includes retrieved ozone concentrations, formal uncertainties, and diagnostic information processed using the TROPESS project's MUSES optimal estimation algorithm.

Use Cases

• Monitoring global tropospheric ozone pollution based on vertical concentration profiles.
• Validating atmospheric chemistry models using satellite-derived ozone data with formal uncertainties.
• Studying stratospheric ozone layer variability across 26 vertical pressure levels.
• Analyzing long-term ozone trends from 2021 to present using a continuous daily time series.

Strengths

• Provides a continuous daily global record from February 1, 2021, to present.
• Offers high vertical resolution with data reported at 26 distinct pressure levels.
• Includes formal uncertainty estimates for the retrieved ozone values, supporting quantitative analysis.
• Data is produced by NASA's TROPESS project using a peer-reviewed optimal estimation algorithm (MUSES).

Limitations

• Column names and a complete data dictionary are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
• Dataset size and row counts are unknown, complicating download and storage planning.
