Global LAke Surface water Temperature (GLAST): Compound thermal extremes in lakes

<p>This database contains daily maximum temperature, daily minimum temperature, and daily mean temperature for 92,245 lakes globally from 1981 to 2020. These daily time series were derived from hourly simulation data.</p> <p>The database also includes annual statistics of six types of thermal extreme events calculated from the daily lake temperature time series:</p> <ul> <li>daytime hot extreme events (hot day&ndash;mild night)</li> <li>nighttime hot extreme events (mild day&ndash;hot night)</li> <li>compound hot extreme events (hot day&ndash;hot night)</li> <li>daytime cold extreme events (cold day&ndash;mild night)</li> <li>nighttime cold extreme events (mild day&ndash;cold night)</li> <li>compound cold extreme events (cold day&ndash;cold night)</li> </ul> <p>&nbsp;</p> <p>The annual statistics provided for these events include metrics such as frequency, intensity, duration, and total days. Additionally, annual statistics of extreme air temperature events over the lakes are included.</p> <p>Details about the hourly-scale lake temperature simulation methodology can be found in the paper <em>"Global lakes are warming slower than surface air temperature due to accelerated evaporation"</em> (Tong et al., 2023, Nature Water). Definitions and calculation methods for thermal extreme events in lakes and atmosphere are provided in <em>"Day-night compound thermal extremes in lakes"</em> (Tong et al., 2025).</p> <p>For detailed information about the contents of each data file, please refer to the accompanying <strong>readme.docx</strong> file.</p> <p>For more datasets on global aquatic environments, please visit the official website of the Global Aqua Remote Sensing (GARS) Laboratory, led by Prof. Lian Feng:&nbsp; <a href="https://garslab.com/?cat=1">https://garslab.com/?cat=1</a>.</p>
