Context: Thermal Infrared Imaging Satellite for High-resolution Natural Resource Assessment (TRISHNA) mission, a collaboration between ISRO and CNES (French Space Agency), aims to monitor surface temperature and water management globally.
It includes two primary payloads: Thermal Infra-Red (TIR) from CNES for infrared imaging and VNIR-SWIR from ISRO for surface reflectance mapping. Operating in a Sun-synchronous orbit, it will aid climate monitoring, urban planning, and disaster management.
Objectives: The mission aims to monitor the energy and water budgets of continental biospheres, alongside high-resolution observation of water quality and dynamics. It provides detailed monitoring of surface temperature, emissivity, and radiation variables, aiding regional to global surface energy budgeting. Additionally, it assists in assessing urban heat islands, detecting thermal anomalies, and monitoring snow-melt runoff, glacier dynamics, aerosol optical depth, atmospheric water vapour, and cloud cover.
Other Indo-French collaborations to monitor Earth: Megha-Tropiques. Saral
