Data quality assessment

Assessment and monitoring of the performances of the instruments and their derived geophysical datasets is a core activity of CERSAT. It relies both on a team of experts for type of data as well as dedicated tools and resources developed to perform these activities.

Performances

Calibration, validationd and long-term monitoring of the instrument performances and the quality of the retrieved geophysical information is performed in the context of various satellite missions and frameworks, for instance:

This activity also addresses the validation of higher level geophysical products merging several sources of data, as:

Resources

Tools and resources implemented for these activities include validation database (for instance in situ measurement, model data), colocation tools and complete software suites for the analysis of the results.

Example of tools developed by CERSAT include the felyx software solution implemented by ESA.
