Residual extinction transmission spectra from the GOMOS instrument on the Envisat satellite, corrected for scintillation and dilution effects. Data was produced by the European Space Agency (ESA) and last updated in April 2012. Each occultation event generates a file of approximately 1 megabyte.
Use Cases
- Analyzing temporal trends in residual extinction spectra to study atmospheric composition changes.
- Correlating scintillation-corrected transmission data with specific elevation (+62 to +68 deg) and azimuth (+90 to +190 deg) ranges for geometric analysis.
- Validating atmospheric inversion models using pre- and post-inversion transmission spectra from occultation events.
Strengths
- Data is corrected for specific instrumental effects (scintillation and dilution).
- Coverage is defined for specific geometric ranges: elevation +62 to +68 deg and azimuth +90 to +190 deg.
Limitations
- Data recency is limited, with last update in 2012, preceding the end of the Envisat mission.
- Specific data volume (rows), column schema, and complete temporal coverage are unknown.
