Two+ decades (2000-2023) of pan Arctic meltpond fraction data
Melt ponds are influencing the Arctic energy budget as they strongly reduce the surface albedo of sea ice. It is therefore highly important to monitor their temporal and spatial evolution.

Melt ponds are influencing the Arctic energy budget as they strongly reduce the surface albedo of sea ice. It is therefore highly important to monitor their temporal and spatial evolution.

To do so we make use of a spectral unmixing algorithm implemented via a neural network to reduce computational costs.
