MetOp GOME-2 instruments provide global atmospheric trace gas data, with emphasis on ozone distributions and Bromine Monoxide (BrO) total columns. The dataset is generated by DLR for EUMETSAT's AC-SAF using the GDP 4.x algorithm within the UPAS processor. Near-real-time products are available approximately two hours after satellite sensing.
Use Cases
- Analyze global BrO total column trends over time to study polar ozone depletion events.
- Correlate BrO measurements with cloud property data from the same instrument to understand atmospheric transport.
- Validate chemical transport models using near-real-time trace gas column observations.
- Monitor spatial distributions of atmospheric bromine compounds for pollution detection studies.
Strengths
- Data continuity from three MetOp satellites launched in 2006, 2012, and 2018, enabling long-term monitoring.
- Near-real-time product availability within two hours of satellite sensing for timely analysis.
- Global spatial coverage from the GOME-2 instrument's measurements.
Limitations
- Specific data volume, row count, and temporal resolution are not provided in the input.
- The description lacks details on data granularity, potential gaps, or validation status against ground measurements.
