ISRO's TRISHNA Mission: Indo-French Collaboration for Global Climate Monitoring
| Aspect | Details |
|---|---|
| Mission Name | TRISHNA (Thermal Infra-Red Imaging Satellite for High-Resolution Natural Resource Assessment) |
| Agencies Involved | ISRO (India) and CNES (France) |
| Objective | Monitor surface temperature and water management globally |
| Launch Year | Tentatively 2025 |
| Expected Lifespan | 5 years |
| Key Focus Areas | Evapotranspiration, water presence, melting glaciers, thermal anomalies, urban heat islands |
| Atmospheric Studies | Aerosols, water vapour, clouds |
| Primary Payloads | Thermal Infra-Red (TIR) by CNES; Visible Near Infrared-Red Short Wave Infrared-Red (VNIR-SWIR) by ISRO |
| TIR Payload Function | Four-channel long-wavelength infrared imaging sensor for high-resolution surface temperature |
| VNIR-SWIR Payload Function | Seven-band mapping of earth's surface reflectivity (albedo) and biophysical variables |
| Expected Benefits | Boost remote sensing technology, address water and food security, aid climate change mitigation |
| Target Users | Watershed managers, agro-industries, farming community in India |
