TROPESS: Satellite Ozone Vertical Profiles

26 vertical levels from the surface to 0.1 hPa provide a detailed atmospheric ozone profile. This dataset contains the vertical distribution of ozone (O3) and formal uncertainties retrieved from the AIRS instrument on Aqua and the OMI instrument on Aura satellites. The NASA TROPESS project uses the MUSES optimal estimation algorithm to produce daily global data from February 2021 onward.

Use Cases

• Monitoring global tropospheric ozone trends based on daily vertical profiles.
• Assessing ozone layer variability and recovery based on measurements from 26 pressure levels.
• Validating atmospheric models using satellite-derived ozone concentrations and formal uncertainties.
• Studying the spatial distribution of ozone using data with a 13 km x 24 km nadir resolution.

Strengths

• Provides data at 26 vertical levels, offering detailed atmospheric stratification.
• Uses a multi-sensor optimal estimation algorithm (MUSES) for retrieval.
• Has a defined global time coverage starting from 2021-02-01.
• Is available on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating importance.

Limitations

• Column names are unknown across all sources, limiting precise understanding of data structure.
• Key metadata like row count, size, and author are unspecified.
• The license is listed as 'other-license-specified' without further detail.
