OMO3PR: Ozone Profile Data from Aura Satellite

Global satellite data provides ozone concentration profiles across 18 atmospheric layers, measured in Dobson units. The OMO3PR product is derived from the Aura Ozone Monitoring Instrument using an optimal estimation algorithm on UV spectral radiance. Each file contains data from the sunlit portion of an orbit, with a nadir pixel resolution of 13 by 48 kilometers.

Use Cases

• Monitoring stratospheric ozone depletion based on vertical profile data.
• Validating atmospheric chemistry models using the provided averaging kernel and error covariance matrix.
• Studying diurnal and seasonal ozone variations using time, latitude, and longitude coordinates.
• Assessing satellite retrieval algorithm performance by comparing a-priori and retrieved ozone profiles.

Strengths

• Provides data for 18 distinct atmospheric layers, enabling detailed vertical profile analysis.
• Includes algorithm diagnostic information such as averaging kernels and error covariance matrices.
• Has a high spatial resolution of 13x48 km at nadir for Level-2 satellite data.

Limitations

• Metadata completeness is low; specific column names, row counts, and temporal coverage are not provided in the sources.
• Data volume is approximately 150 GB per day, which may present storage and processing challenges.
• One source lists a license as 'other-license-specified' while another lists 'None', creating ambiguity.
