LST陆面温度

地表温度是指地面的温度，太阳的热能被辐射到达地面后，一部分被反射，一部分被地面吸收，使地面增热，对地面的温度进行测量后得到的温度就是地表温度。通过Landsat/MODIS等卫星的多光谱通道进行反演计算，可生产30m、250m、1km等分辨率的LST产品，时间频率可达小时级。

Land Surface Temperature (LST) refers to the temperature of the Earth's surface. When solar thermal energy reaches the ground via radiation, a portion is reflected and the remainder is absorbed by the ground, leading to surface heating; the temperature obtained through ground surface temperature measurements is LST. Through inversion calculations using multispectral channels of satellites such as Landsat and MODIS, LST products with resolutions of 30 m, 250 m, 1 km and other specifications can be generated, with a temporal frequency up to hourly.
