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.

Statement

The main input datasets are daily MODIS products MOD09GQ and MYD09GQ at 250m and MOD10A1 and MYD10A1 at 500m spatial resolution. Additional auxiliary datasets, such as DEM, MOD44W and the ESA-CCI Water Bodies Map v4.0 are included within the pre- and postprocessing. For more information please refer to Klein et al. 2017.
Description

The main classification step is based on an automatic dynamic thresholding based daily data input. In a second step, a temporal interpolation is performed for all pixels which were covered by clouds or had low quality. For more information please refer to Klein et al. 2017.
