Abstract

In this paper, a description of the thermal radiometric measurements carried out in the framework of the Spectra Barrax Campaign (SPARC) is presented. The purpose of these measurements is to retrieve biogeophysical parameters such as land surface emissivity and temperature to analyze the relationship of these parameters with fluorescence. The in situ data base was used to validate high and low resolution sensors such as Airborne Hyperspectral Scanner (AHS), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Spinning Enhanced Visible and Infrared Imager (SEVIRI) and Advanced Along-Track Scanning Radiometer (AATSR), and a synergistic study was firstly developed between SEVIRI and ASTER and secondly between AATSR and CHRIS/PROBA (Compact High Resolution Imaging Spectrometer/ Project for On Board Autonomy). The thermal measurements were carried out basically using two multiband field radiometers (CIMEL CE 312-1 and 312-2) and several single band field radiometers (RAYTEK ST6, RAYTEK MID and EVEREST 3000.4ZLC), pointing at different targets (soil, vegetation, sky). Transects, angular and emissivity measurements were carried out and the results show the importance of thermal measurements to characterize the different surfaces over the test area.
