TROPESS OMI-Aura: Daily Global Ozone Vertical Profiles

From February 2021 to present, this dataset provides daily global measurements of the vertical distribution of atmospheric ozone (O3) and its uncertainties. The data is produced by the NASA TROPESS project using the MUSES optimal estimation algorithm from the OMI instrument on the EOS Aura satellite. Each file contains one day of data reported at 26 vertical levels from the surface to 0.1 hPa.

Use Cases

• Monitoring stratospheric ozone depletion based on vertical profiles from 26 levels.
• Analyzing tropospheric ozone pollution trends using global daily measurements.
• Validating atmospheric chemistry models with satellite-derived ozone state and formal uncertainties.
• Studying spatial patterns of ozone concentration using data with 13 km x 24 km nadir resolution.

Strengths

• Provides a continuous global time series from February 2021 onward.
• Offers detailed vertical resolution with profiles reported at 26 distinct pressure levels.
• Includes formal uncertainty estimates for each retrieved ozone measurement.

Limitations

• Column names and specific variable details are not provided in the metadata.
• The dataset's size and row count are unknown across all sources.
• License information is inconsistently reported as 'other-license-specified' or null.
