Artifacts
What each model built on each task, shown on the held-out cases it was graded on.
Storm surge forecast
Each model forecast a design storm’s water level, tide plus surge plus wave setup, at 25 points on a barrier-island coast for 24 hours; a value earns credit only within 5 cm of the truth. These are graded hidden test values at three of the points, for each model’s best and median attempt.
