Title : “A multiscale/multi-temporal study of Lake Surface Water Temperature (LSWT) using thermal satellite sensors: application to lakes of Grand-Est region, France, and Kyrgyzstan”

Abstract :

The Lake Surface Water Temperature (LSWT) significantly impacts the aquatic environment and water chemistry, making it a crucial indication of the lakes' health. Moreover, the LSWT influences the weather and atmosphere surrounding the big lakes. Many applications, including studies of the hydrological cycle and climate change, the habitat of aquatic creatures, fisheries, aquaculture, and water quality management, require data on water temperature with increased spatial and temporal resolutions. This research aims to acquire and analyze the LSWT using TIR satellite sensors such as Landsat 8-9, ECOSTRESS, Sentinel-3, and MODIS. These sensors provide valuable information in anticipation of new TIR missions such as TRISHNA in 2025 (CNES-ISRO), LSTM (ESA Copernicus), and SBG (NASA), both in 2028. The study estimates LSWT from the Issyk-Kul Lake, Kyrgyzstan, and the Gerardmer, Longemer, and Plobsheim Lakes, France. To assess the LSWT, multisensors providing denser spatial and temporal LSWT estimates are needed to understand processes and dynamics in the thermal domain. In addition, the LSWT estimates from the satellites were validated by intercomparisons and in-situ campaigns over the mentioned lakes during different year periods.
