Isro, which has been planning a joint satellite called “Trishna” with the French National Centre for Space Studies (CNES) for several years, on Wednesday spelt out some details about the mission, but did not give out a specific timeline.
The Thermal Infra-Red Imaging Satellite for High-resolution Natural Resource Assessment or Trishna mission will provide high spatial and temporal resolution monitoring of Earth's surface temperature, emissivity, and biophysical variables, focusing on addressing water and food security challenges in the face of climate change.
The primary objectives of the mission include detailed monitoring of the energy and water budgets of Earth’s surface, high-resolution observation of water quality and dynamics, and assessment of urban heat islands, Isro said.
It added that the satellite will also detect thermal anomalies linked to volcanic activity and geothermal resources, and monitor snow-melt runoff and glacier dynamics.
“Equipped with a Thermal Infra-Red (TIR) payload from CNES and a Visible - Near Infra-Red - ShortWave Infra-Red (VNIR-SWIR) payload from Isro, Trishna will operate in a sun-synchronous orbit at an altitude of 761 km. The mission is designed for a 5-year operational life and will provide data with a spatial resolution of 57m for land and coastal areas and 1km for oceanic and polar regions,” Isro said.
Isro added that Trishna’s data will contribute to several global initiatives, such as GEOGLAM (Group on Earth Observations Global Agricultural Monitoring) for agricultural monitoring, UN’s Sustainable Development Goals, and the Global Water Watch.
The mission’s outputs will serve as Essential Agricultural Variables (EAVs) and Essential Climate Variables (ECVs) for the global community, Isro said.
