Summary

The purpose of this joint research between Instituto de Agricultura Sostenible (IAS-CSIC) and Instituto Nacional de Técnica Aeroespacial (INTA), in collaboration with the Universidad de Valencia (UV) is to investigate thermal and hyperspectral satellite and airborne remote sensing radiative transfer methods for water stress and photosynthetic functioning quantification. Research proposed here aims to investigate physical methods to estimate crop biophysical variables, biochemical constituents and water stress detection from thermal and hyperspectral remote sensing imagery. These objectives are joint to a funded project AGL2004-05717 which goals are to learn about carbon sequestration and water productivity in olive canopies. Work proposed here will take advantage of leaf and canopy datasets that will be collected as part of the mentioned funded project, adding a new spatial and temporal scale using remote sensing imagery. This work will connect leaf biochemical and canopy biophysical estimates from remote sensing data collected over olive groves under different irrigation schemes with photosynthetic functioning and water status at the tree level. Satellites used will be of high and medium spatial resolution (Quickbird and ASTER), and airborne sensor AHS, collecting data in the 400-2500 nm range and in the thermal region.
