1. INTRODUCTION
During the two years 2023-2025 of THERESA project, founded by ASI, Istituto Nazionale di Geofisica e Vulcanologia (INGV) will analyze specific algorithms and products for various geophysical and volcanological applications to be used on the data that will be acquired during the lifetime of the next SBG-TIR mission. This is a visible and thermal infrared (VIS-TIR) mission aiming to do routinely observations and to characterize the earth surface by coupling panchromatic, visible and thermal sensors.
