This working group grew out of the mission validation and Adopt-A-Crossover campaigns. We
- focus on satellite validation activities
- aimed at understanding SWOT observations and derived products—most notably sea surface height (SSH),
- evaluate SWOT measurements by comparing against independent “ground-truth” observations, typically in-water or near-surface measurements.
The primary goal is to assess the quality and limitations of SWOT observations and products, and to provide actionable feedback and recommendations to the mission team to guide improvements in future data releases.
