# Cryo-Bench ๐ง
> **A Benchmark for Evaluating Geospatial Foundation Models on Cryosphere Applications**
[](https://arxiv.org)
[](https://arxiv.org/abs/2412.04204)
[](LICENSE)
**Cryo-Bench** is a community benchmark that evaluates geospatial foundation models (GFMs) on five cryosphere remote sensing tasks spanning glacial lakes, supraglacial debris, sea ice, and calving fronts. It is built on top of the [PANGAEA](https://arxiv.org/abs/2412.04204) evaluation protocol using multi-sensor satellite imagery from Sentinel-1/2, Landsat-8, WorldView-2, and historical SAR missions.

## ๐งฐ Code
The full benchmarking code is available in the [`Cryo-Bench Github/`](https://github.com/Sk-2103/Cryo-Bench/) directory, which contains dataset configs, encoder definitions, and decoder heads built on top of [PANGAEA](https://arxiv.org/abs/2412.04204).
## ๐ Tasks & Datasets
Cryo-Bench includes five benchmark tasks covering key components of the cryosphere:
