Extracting quantitative information from satellite data : Empirical and physical approachesFunded under: JRC-REMSENS 4C
This study investigates the usefulness of currently available satellite data in providing quantitative information for modelling or monitoring the climate system. In this context, vegetation indices provide a simple tool to explore or quickly evaluate the state of the surface, but several sources of variation render their interpretation more difficult. On the other hand, a physically-based approach appears to be able, in principle, to provide comprehensive and unambiguous information on the observed target, compatible with modelling requirements and global monitoring. The research presented in this book shows that application of the physically-based approach can improve the interpretation of current satellite data. It emphasises the capabilities of that approach and considers what may become possible in a few years when better models and improved satellite data will be available.
