EarthCARE auxiliary data products encompass essential supporting datasets for accurate sensor data processing and analysis. The European Space Agency (ESA) provides these datasets, which include calibration parameters, ground control data, digital elevation models, and reconstructed orbit and attitude files. This data is integrated into the EarthCARE mission's workflow to ensure high-quality outputs for atmospheric and climate research.
Use Cases
- Apply calibration parameters to correct raw sensor measurements from EarthCARE's instruments.
- Use ground control data for validating the geolocation accuracy of primary EarthCARE data products.
- Integrate digital elevation data to enable precise terrain correction for atmospheric retrievals.
- Utilize reconstructed orbit and attitude files to model the satellite's exact position and orientation during data acquisition.
- Combine auxiliary and orbit data to produce high-level scientific datasets for climate model evaluation.
Strengths
- Data is essential for producing high-quality primary datasets from the EarthCARE mission.
- Integrates multiple critical data types: calibration parameters, ground control, elevation, and orbit data.
Limitations
- Specific row counts, file sizes, and temporal coverage are not provided in the description.
- The dataset's utility is highly specialized and dependent on access to the primary EarthCARE sensor data streams.
