Global WaterPack - MODIS - Daily

The Global WaterPack is a dataset containing information about open surface water cover parameters on a global scale. The water detection is derived from daily, operational MODIS datasets for every year since 2003. The negative effects of polar darkness and cloud coverage are compensated by applying interpolation processing steps. Thereby, a unique global dataset can be provided that is characterized by its high temporal resolution of one day and a spatial resolution of 250 meter. The daily binary layers in this collection contain information whether a pixel was detected as open surface water (1) or not (0). Furthermore, reliability and observation layers provide additional information on the quality of each Global WaterPack pixel.

全球水数据集（Global WaterPack）是一套涵盖全球尺度开阔地表水覆盖参数信息的数据集。其水体检测结果源自2003年以来每年的业务化运行中分辨率成像光谱仪（MODIS）每日数据集。通过插值处理流程，可抵消极地黑暗与云覆盖所带来的负面影响。借此可构建兼具单日高时间分辨率与250米空间分辨率的独特全球数据集。该集合中的每日二值图层存储有像素是否被识别为开阔地表水的信息：标记为1代表存在开阔地表水，0则代表不存在。此外，可靠性图层与观测图层可为每个Global WaterPack像素的质量提供额外辅助信息。
