Analyzing Lakes Surface Temperature Variability at the Global Scale

Lake Surface Water Temperature (LSWT) is recognized as a critical climate change indicator. The changes in surface water temperature and the temperature of the surrounding land may have a climate change signature if there is consistency between changes in both temperatures. This proj ect focuses on the application of remote sensing to investigate the changes in lake surface water temperatures and their relationship with the surrounding land cover type to identify the main driving factors of these changes. In this study, 507 major global lakes have been investigated. An analysis of temperature variation over these lakes has been conducted using daily observations of Aqua MODIS from 2002 to 2018. Preliminary results show that 43.15% of the studied lakes are warming and about 51.00% of lakes are cooling. Furthermore, 62.53% of the lakes are shrinking, while 28.35% of them are expanding.
