Daily Quality Reports

The Daily Reports were produced on a daily basis by the SPPA AATSR Quality Control team, and were primarily intended for ESA internal use only. These checks were limited to the analysis of data available at the end of each day, and so should not be relied upon as a definitive source of information on the unavailability or quality of instrument data.

Cyclic Quality Report

The Cyclic Reports were distributed by ESA to keep the AATSR Community informed of any modification regarding the processor, updates of auxiliary products, anomalies of the instrument behaviour, data acquisition and processing, and finally the status of the calibration, validation, and quality control activities. The Report collects the inputs coming from different groups involved in AATSR data exploitation: SPPA and the QC Team, the Quality Working Group, the MERIS/AATSR validation team, Rutherford Appleton Laboratory and the University of Leicester.
