TRPSDL2O3AIRSOMIFS: Satellite Vertical Ozone Profiles

26 vertical levels from the surface to 0.1 hPa provide the vertical distribution of atmospheric ozone (O3). The NASA TROPESS project uses the MUSES optimal estimation algorithm to combine measurements from the AIRS instrument on Aqua and the OMI instrument on Aura. Daily netCDF files contain retrieved ozone state, formal uncertainties, and diagnostic information globally from February 2021 onward.

Use Cases

• Monitoring stratospheric ozone layer health based on vertical profiles from 0.1 hPa to surface.
• Analyzing tropospheric ozone pollution transport using the 13 km x 24 km nadir spatial resolution.
• Assessing satellite retrieval algorithm performance using the formal uncertainties and diagnostic information.
• Studying global ozone trends and variability from the continuous daily data stream starting in 2021.

Strengths

• Combines data from two satellite instruments (AIRS on Aqua and OMI on Aura) for a multi-sensor product.
• Provides high vertical resolution with profiles reported at 26 discrete levels.
• Offers a continuous, global time series from February 1, 2021 to the present.

Limitations

• Column names and detailed variable metadata are not provided in the available descriptions.
• The dataset's license is inconsistently reported as 'other-license-specified' or 'None' across platforms.
• The exact file size and total row count are unknown.
