TIRLab - Thermal Infrared Remote Sensing

The TRISHNA (Thermal Infra-Red Imaging Satellite for High-resolution Natural Resource Assessment) mission, a collaborative endeavor between ISRO and CNES, is launching in 2027. It will carry unprecedented high resolution thermal data to study the energy and water budgets of the continental biosphere for quantifying terrestrial water stress and use,  observation of water quality and dynamics in coastal and inland waters, urban heat island effects and cryospheric surface. To know more on the mission check the new preprint with the whole TRISHNA consortium where TIRLab is part of submitted to EGU - Earth Observation Journal at this link

In a joint effort from our group in collaboration with NASA Jet Propulsion Laboratory, we just published a preprint entitled "Airborne TIR imaging spectroscopy reveals debris-covered glaciers' surface lithology, emissivity, and their impact on land surface temperature". In this work we exploited a novel airborne hyperspectral TIR dataset over a debris-covered glacier to map different lithologies, link them to their source, and investigate the representativeness of commonly used emissivity values for supraglacial debris. The work has been submitted to Remote Sensing of Environment. The preprint is available at this link

Gabriele Bramati and Kathrin Naegeli's paper entitled "A Correction Methodology for Cross-Track Instrument Biases in Airborne Hyperspectral Thermal Infrared Data Over the Cryosphere" was just published in IEEE Geoscience and Remote Sensing Letters. In the study, we developed a correction methodology for airborne hyperspectral TIR data over alpine glaciers and validated againts in-situ measurements. The publication is available at this link
