Google Earth Engine ——MYD11A1 V6产品提供1200×1200公里网格内的每日陆地表面温度（LST）和发射率值数据集

The MYD11A1 V6 product provides daily land surface temperature (LST) and emissivity values in a 1200 x 1200 kilometer grid. The temperature value is derived from the MOD11_L2 swath product. Above 30 degrees latitude, some pixels may have multiple observations where the criteria for clear-sky are met. When this occurs, the pixel value is the average of all qualifying observations. Provided along with both the day-time and night-time surface temperature bands and their quality indicator layers are MODIS bands 31 and 32 and six observation layers.

MYD11A1 V6产品提供1200×1200公里网格内的每日陆地表面温度（LST）和发射率值。温度值来自MOD11_L2 扫频产品。在纬度30度以上，一些像素可能有多个符合晴空标准的观测。当这种情况发生时，像素值是所有符合条件的观测值的平均值。与白天和夜间地表温度带及其质量指标层一起提供的还有MODIS 31和32带以及六个观测层。
