Thesis title: Standards for the validation of geophysical remote sensing products

My research is focused on developing quality assurance frameworks for field measurements of land Essential Climate Variables (ECVs) such as land surface albedo, LAI and FAPAR. In support of Copernicus and projects such as QA4ECV, quality assurance information needs to be provided at every step in the processing chain for the provision of ECVs, for both space-based retrievals and the in-situ retrievals used to validate the satellite products. The proper quantification of quality information for in-situ measurements is crucial, as accurate in-situ measurements with appropriate uncertainties are required to properly validate remote sensing products.

Using a model-based approach with Monte Carlo Ray Tracing (MCRT) radiative transfer models, the aims of my thesis are twofold:

1. Develop unbiased approaches for assessing the quality of in situ measurements and their protocols for LAI, FAPAR and land surface albedo.

2. Assess the performance of CEOS recommended field validation protocols for selected land ECVs

The objectives of this research are therefore to provide quality information for in-situ measurements, to assess specific contributions to uncertainty and to test conformity to accuracy requirements for the use of in-situ measurements to validation space-based retrievals. The development of a quality assurance framework using this method can also help field measurement communities in setting up their measurement protocol to yield the most accurate measurements or assign quality information to already existing measurement protocols.
