Fiducial Reference Measurements (FRM) are a suite of independent, fully characterized, and traceable ground measurements that follow the guidelines outlined by the GEO/CEOS Quality Assurance framework for Earth Observation (QA4EO). These FRM provide the maximum Return On Investment (ROI) for a satellite mission by delivering, to users, the required confidence in data products, in the form of independent validation results and satellite measurement uncertainty estimation, over the entire end-to-end duration of a satellite mission. Within this context, the SPPA team manages a series of projects targeting the validation of ESA altimetry, atmosphere, land, and ocean products.
FRM4STS is an ESA funded project, to establish and maintain SI traceability of global Fiducial Reference Measurements (FRM) for satellite derived surface temperature product validation. The project will facilitate international harmonisation and interoperability through organisation of a set of inter comparisons under the Committee for Earth Observation Satellites (CEOS) and its Working Group on Calibration and Validation (WGCV).
