TROPESS CrIS-SNPP L2 Ozone: Vertical Profiles During Australian Fires

From November 1, 2019 to January 31, 2020, this dataset provides vertical ozone profiles measured by the Suomi-NPP satellite's CrIS instrument over Australia during wildfire outbreaks. It contains retrieved ozone concentrations, formal uncertainties, and diagnostic information at 26 vertical levels from the surface to 0.1 hPa. The data is processed using the NASA TROPESS project's MUSES optimal estimation algorithm and is stored in daily netCDF files.

Use Cases

• Analyzing the impact of Australian wildfires on atmospheric ozone concentrations based on vertical profiles.
• Validating atmospheric chemistry models using satellite-derived ozone data with formal uncertainties.
• Studying tropospheric ozone distribution and transport during a specific fire season.
• Assessing the performance of the MUSES optimal estimation algorithm for ozone retrieval.

Strengths

• Provides high vertical resolution with data reported at 26 distinct pressure levels.
• Focuses on a specific, significant event (Australian wildfires) over a defined three-month period.
• Includes formal uncertainty estimates for the retrieved ozone values, supporting quantitative analysis.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• The dataset's spatial coverage is limited to a single region (60S-0S, 100E-177.5E).
• Platforms list conflicting 'last updated' dates (2026-04-09 and 2020-01-31), indicating potential metadata inconsistency.
