THERESA project: a study to enhance algorithms for processing data from the SBG-TIR mission in volcanological field

The THERESA project, which stands for THErmal infRarEd SBG Algorithms, seeks to improve algorithms for processing data obtained from the SBG-TIR (Surface Biology and Geology – Thermal InfraRed) mission. By leveraging the mission's technical features, THERESA aims to improve and adapt specific algorithms to study geological processes and develop new ones that could get advantages by using SBG-TIR spectral channels in the VIS and MIR-TIR range. Over the two-year duration of the project, THERESA will play a vital role in advancing the study of terrestrial phenomena also considering the high revisit time of SBG, which will be of 3 days worldwide over land. SBG-TIR data will benefit diverse thematic areas, ranging from vegetation analysis to monitoring volcanic eruptions and fires. The project aims to derive several key parameters, including the estimation of ash and SO2 emissions from volcanoes, surface temperature, detection of hotspots, and the calculation of FRP (Fire Radiative Power) during High Temperature Events (HTEs). THERESA distinguishes itself through its innovative algorithmic advancements, providing comprehensive support to the SBG-TIR mission. Finally, suitable sites for CAL/VAL activities will be identified, and measurement campaigns will be conducted coinciding with the passages of currently operational TIR satellites for the validation of the algorithms under study.
