In this study, data from MODIS land surface temperature product level 3 (MOD11A2) were used to investigate the spatiotemporal variation of Eurasian lakes water surface temperature (LSWT) from 2001 to 2015, and to examine the most influencing factors of that variation. The temperature of most lakes in the dry climate zone and in the equatorial climatic zone varied from 17 to 31°C and from 23 to 27°C, respectively. LSWTs in the warm temperate and cold climatic zones were in the range of 20 to 27°C and −0.6 and 17°C, respectively. The average day time LSWT in the polar climate zone was −0.71°C in the summer. Lakes in high latitude and in the Tibetan Plateau displayed low LSWT, ranging from −11 to 26°C during the night time. Large spatial variations of diurnal temperature difference (DTD) were observed in lakes across Eurasia. However, variations in DTDs were small in lakes located in high latitude and in tropical rainforest regions. The shallow lakes showed a rapid response of LSWT to solar and atmospheric forcing, while in the large and deep lakes, that response was sluggish. Results of this study demonstrated the applicability of remote sensing and MODIS LST products to capture the spatial–temporal variability of LSWT across continental scales, in particular for the vast wilderness areas and protected environment in high latitude regions of the world. The approach can be used in future studies examining processes and factors controlling large scale variability of LSWT.

利用MODIS地表温度产物监测欧亚大湖水面温度。

在这项研究中，MODIS地表温度产品3级（MOD11A2）的数据用于调查2001年至2015年欧亚湖泊水面温度（LSWT）的时空变化，并研究影响该变化的最主要因素。干旱气候区和赤道气候区大多数湖泊的温度分别为17至31°C和23至27°C。温暖的温带和寒冷的气候区的低水WT分别在20至27°C以及-0.6和17°C的范围内。夏季，极地气候区的平均白天LSWT为-0.71°C。高纬度的湖泊和青藏高原的LSWT较低，夜间为-11至26°C。在整个欧亚大陆的湖泊中，观察到昼夜温差（DTD）的较大空间变化。然而，在高纬度的湖泊和热带雨林地区，DTD的变化很小。浅水湖泊显示出LSWT对太阳和大气强迫的快速响应，而在大湖泊和深水湖泊中，该响应缓慢。这项研究的结果表明，遥感和MODIS LST产品可用于捕获LSWT在整个大陆范围内的时空变化，特别是适用于世界上高纬度地区的广大荒野地区和受保护的环境。该方法可用于将来的研究中，以检查控制LSWT大规模变异的过程和因素。该反应迟钝。这项研究的结果表明，遥感和MODIS LST产品可用于捕获LSWT在整个大陆范围内的时空变化，特别是适用于世界上高纬度地区的广大荒野地区和受保护的环境。该方法可用于将来的研究中，以检查控制LSWT大规模变异的过程和因素。该反应迟钝。这项研究的结果表明，遥感和MODIS LST产品可用于捕获LSWT在整个大陆范围内的时空变化，特别是适用于世界上高纬度地区的广大荒野地区和受保护的环境。该方法可用于将来的研究中，以检查控制LSWT大规模变异的过程和因素。
