A high-resolution January surface meltwater dataset reveals interannual variability and recurrent meltwater zones on the Amery Ice Shelf from 2005 to 2026
Listed in ScienceDB
This dataset provides annual January surface meltwater products for the Amery Ice Shelf, East Antarctica, from 2005 to 2026.
Description
The dataset was generated from Landsat 7 ETM+, Landsat 8 OLI and Sentinel-2 MSI optical imagery using a weakly supervised, source-adaptive semantic segmentation framework. The released records include annual binary surface meltwater extent maps, annual surface meltwater area statistics and a multi-year surface meltwater occurrence-count product.
The raster products are provided as GeoTIFF files in the Antarctic Polar Stereographic coordinate system on a common 10 m product grid and are clipped to the Amery Ice Shelf mapping domain. The dataset is intended to support analyses of peak-season surface meltwater extent, interannual variability, recurrent meltwater locations and surface drainage organization on the Amery Ice Shelf.
