Save the date : 1st TRISHNA Workshop in March 2022 in Toulouse
Toulouse, France, 22-24 March 2022
Important note: this page is for information only. Registration and call for abstracts will be available soon on a dedicated website.
Monitoring accurately the water cycle at the Earth surface is becoming extremely important in the context of climate change and population growth. It also provides valuable information for a number of practical applications: agriculture, soil and water quality assessment, irrigation and water resource management, etc… It requires surface temperature measurements at local scale. Such is the goal of the Indian-French high spatio-temporal TRISHNA mission (Thermal infraRed Imaging Satellite for High-resolution Natural resource Assessment), led by ISRO (Indian space agency) and CNES (French Space agency). It will be launched in late 2024/beginning of 2025.
The surface temperature and its dynamics are precise indicators of the evaporation of water from soils, transpiration of plants and of the local climate. TRISHNA and its frequent high-resolution measurements raise major scientific, economic and societal issues through the 6 major themes that the mission addresses from the angle of research and development of applications: ecosystem stress and water use; coastal and inland waters; monitoring of the urban climate; cryosphere; solid Earth; atmosphere.
The objective is to gather all people involved and interested in the science and applications in which TRISHNA will contribute: contributors to the design of the mission or elaboration of the products and potential users. This first international workshop shall be a key milestone in order to converge on TRISHNA science plan, including CAL/VAL activities, scientific algorithms for data processing, product definition, with enhanced coordination between all partners.
Discussions and exchanges will include:
TRISHNA in the international context
All discussions within the workshop shall be considered in synergy with the future operational missions with high resolution and high revisit thermal infrared capability (TRISHNA, Copernicus’ LSTM, NASA’s SBG), and based on the experience gathered with the pathfinder missions (LANDSAT, ASTER, ECOSTRESS)
Elaboration of TRISHNA products and Calibration/Validation
- The definition of TRISHNA scientific products and variables
- Requirements and constraints for the distribution of the products to the users
- The elaboration of the products, through the redaction of the Algorithm Theoretical Basis Documents
- Calibration and validation activities
TRISHNA scientific themes and associated applications
- Ecosystem stress and water use: advances in the assimilation of land surface temperature or evapotranspiration in hydrological models
- Coastal and inland waters
- Urban climate modeling
- Solid earth
The workshop will last for 3 days. It will include a series of plenary presentations.
Furthermore, specific themes and issues will be discussed in follow-up breakout sessions. The outcomes of the breakout sessions will be presented in plenary by the respective moderators followed by open discussion.
Following the workshop, the proceedings (presentations, discussion summaries and
conclusions) will be prepared and made available to participants and other interested parties on the TRISHNA website.
The working language of the workshop will be English.
