The Global Climate Observing System (GCOS) of the World Meteorological Organization (WMO) has recognized “Lakes” as one of its Essential Climate Variables (ECVs). Amongst the lake variables identified as sensitive indicators of climate change are lake surface temperature, lake area, lake water level, and more recently added are ice freeze-up and break-up dates. This decade has seen and will continue to see the launch of an unprecedented number of Earth Observation satellites from space agencies that will offer an extraordinary opportunity to observe changes and variability in these lake properties over high-latitude northern regions. This also happens at a time when unmanned aerial vehicles (UAVs), which can fill a critical measurement gap between field measurements and satellite imagery, are increasingly becoming available for rapid deployment in order to capture more local changes in lake properties occurring at even shorter time scales.

世界气象组织（WMO）的全球气候观测系统（GCOS）已将“湖泊”作为其基本气候变量之一。在被确定为气候变化敏感指标的湖泊变量中，有湖泊表面温度、湖泊面积、湖泊水位，以及最近增加的冰冻结和破裂日期。在这十年里，太空机构发射了数量空前的地球观测卫星，并将继续发射这些卫星，这将为观察高纬度北部地区这些湖泊属性的变化和可变性提供难得的机会。这种情况也发生在无人驾驶飞行器（uav）能够填补现场测量和卫星图像之间的关键测量空白的时候，无人机越来越多地用于快速部署，以便在更短的时间尺度上捕捉更多的局部湖泊属性变化。
