# ExtremeEventSensor
This dataset accompanies the NeurIPS 2026 paper *Mechanism-Aware Ensemble Conditioning for Data-Limited Emulation of Extreme Events*.
**TLDR:** Small ensembles of perturbed, low-cost simulations reveal locally unstable directions in the dynamics. We use that information to guide learned corrections to coarse trajectories.
## What’s included
- **LowDim:** Trajectories from a three-dimensional nonlinear system exhibiting bursts, including reference, coarse, nudged, and perturbed ensemble simulations.
- **QG:** Data from a two-layer quasigeostrophic model, including upper and lower streamfunction with additional topography. Includes fields from reference, coarse, nudged, and ensemble simulations.
For a short demonstration, see the [blog post](https://www.mit.edu/~thieli/writing/neurips/). Full details about methods and examples are in the [paper](https://arxiv.org/abs/2609.30746), and the accompanying code is on [GitHub](https://github.com/thisisisi/ExtremeEventSensor). |
