Released under Apache 2.0 as the supervision component of the [GLOFcast](https://github.com/abzalabdrash/glofcast) operational early-warning system. This model card documents the **Stage 4b v2 production soup** — a uniform weight-space average of five SWA snapshots from the Almaty-corridor finetune. It is the recommended checkpoint for inference. ## Key results | Metric | Value | |---|---:| | Validation IoU @ thr = 0.5, TTA on (n = 666) | **0.9557** | | Validation IoU @ best thr (0.70), TTA on | 0.9596 | | Held-out test IoU @ thr = 0.5, TTA on (n = 665) | 0.8918 | | Held-out test IoU, label-corrected (n = 658) | **0.9082** | Comparison to literature — same train/val protocol as Adhikari & Regmi (2025), arXiv:2512.24117: | Reference | Modality | Val IoU | |---|---|---:| | Adhikari & Regmi (2025) | S1 only | 0.9130 | | **CryoSentinel (this model)** | **S1 + S2 + DEM** | **0.9557** | ## Model details - **Architecture**: TerraMind 1.0 Large encoder (1.1 B parameters; Jakubik...
