OlmoEarth-v1-Potomac-Sewage-Spill-2026数据集是一个经过验证、时间对齐的参考数据集，支持GeoAI跟踪2026年波托马克河污水泄漏事件（马里兰州Glen Echo地区，2026年1月19日从72英寸波托马克拦截器释放了2.4至3亿加仑污水）。数据集提供事件时间线、水文背景、监测站位置和AOI走廊多边形，用于AI2下游Sentinel-1/2羽流检测。数据集包含8个监测站、846条每日流量记录、4阶段时间线和4阶段AOI走廊，覆盖时间为2025年12月至2026年3月。数据集主要用于事件参考和验证，而非训练集。

The OlmoEarth-v1-Potomac-Sewage-Spill-2026 dataset is a validated, time-aligned reference dataset supporting GeoAI tracking of the 2026 Potomac River sewage spill (Glen Echo, MD — 240–300 million gallons released from the 72-inch Potomac Interceptor on January 19, 2026). It provides an event timeline, hydrologic context, monitoring station locations, and AOI corridor polygons for AI2s downstream Sentinel-1/2 plume detection. The dataset includes 8 stations, 846 daily flow records, a 4-phase timeline, and a 4-stage AOI corridor, covering the period from December 2025 to March 2026. It is designed as an event reference / validation dataset, not a training set.
