This is the official dataset for MeltwaterBench: Deep learning for spatiotemporal downscaling of surface meltwater.

This dataset sets up a benchmark for spatiotemporal downscaling. Downscaling is similar to superresolution across space and time. The task is to create high-resolution surface meltwater maps from low-resolution (LR) data streams. The LR data contains passive microwave (PMW), a regional climate model (MARv3.14), a temporal interpolation of the targets from dates excluding the target date (time_interpolate_sar), and a static digital elevation map (DEM).

The generated 100m daily surface meltwater product can be found at interim/runs/unet_smp/data_v1_4/deploy/. You can download individual files by clicking the 'download' button.

For downloading the full dataset and training models use the following or see full instructions at https://github.com/blutjens/meltwaterbench:
