TROPESS CrIS-JPSS1: Daily Global Ozone Vertical Profiles

26 vertical levels from the surface to 0.1 hPa provide the atmospheric state of ozone measured by the CrIS instrument on the NOAA-20 satellite. The dataset contains retrieved ozone concentrations, formal uncertainties, and diagnostic information for each day from April 2021 onward. It is produced by the NASA TROPESS project using the MUSES optimal estimation algorithm.

Use Cases

• Monitoring global tropospheric ozone trends based on daily vertical profiles.
• Assessing model performance by comparing simulated ozone with satellite retrievals and their formal uncertainties.
• Studying stratospheric ozone dynamics using data reported up to 0.1 hPa.
• Analyzing spatial patterns of ozone concentration at a 14 km nadir resolution.

Strengths

• Provides a continuous daily record from April 2021 to present.
• Offers high vertical resolution with data reported at 26 distinct pressure levels.
• Includes formal uncertainty estimates for each retrieval, supporting quantitative analysis.

Limitations

• Column names and exact data structure are not provided in the metadata.
• The dataset size and row count are unknown across all sources.
• License information is inconsistently reported as 'other-license-specified' or 'None'.
