Surface meltwater dataset at 30-m resolutionform Alexander Island in the Antarctic Peninsula (2000-2019)

In recent years, the Antarctic Ice Sheet experiences substantial surface melt, and a large amount of meltwater formed on the ice surface. Observing the spatial distribution and temporal evolution of surface meltwater is a crucial task for understanding mass balance across the Antarctic Ice Sheet. This dataset provides a 30 m surface meltwater coverage, extracted from Landsat images, in the typical ablation zone of the ice sheet (Alexandria Island, Antarctic Peninsula) from 2000 to 2019. The projection of this dataset is South Polar Stereographic. The formats of the dataset are vector (.shp) and raster (.tif).

Data file naming and use method

The file is saved as the formats of .shp and .tif and named as "watermask_antarctic_xxx_yyy ”. The XXX is the location of the study area, and the YYY represents the satellite image used to generate data. For example, "waterask_ antarctic_ peninsula_ LC08_ L1GT_ 217111_ 20180120_ 20180206_ 01_ T2" represents this file shows the spatial distribution of surface meltwater across the Antarctic Peninsula using Landsat8 image acquired on January 20, 2018.
