This EarthCARE Auxiliary Data collection is available only to the EarthCARE Commissioning Team and to Principal and Co-Investigators of accepted proposals to the ESA Announcement of Opportunity for the Validation of EarthCARE.

EarthCARE data products encompass essential supporting auxiliary (AUX) and orbit data critical for accurate sensor data processing and analysis.

• AUX data includes datasets used outside the primary Space Segment stream to apply corrections to sensor data. This comprises previously derived calibration parameters, ground control data, and digital elevation data. Calibration parameters ensure measurement accuracy, while ground control data aids in data validation, and digital elevation data enables precise geolocation. 

• Orbit data consists of on-board satellite data and orbital information. For EarthCARE, this includes Reconstructed Orbit and Attitude Files, which provide detailed satellite positioning and orientation information.

The integration of AUX and orbit data into EarthCARE's data processing workflow ensures the production of high-quality, scientifically valuable datasets for atmospheric research, climate modelling, and environmental monitoring.
