1. SWOT will measure water elevation with unprecedented accuracy. The Surface Water and Ocean Topography (SWOT) satellite will measure water elevation over 90% of the Earth's surface with an accuracy of 2 centimeters (0.8 inches). This is a significant improvement over previous satellite missions, which could only measure water elevation with an accuracy of 10 centimeters (4 inches).

2. SWOT will provide global coverage of water bodies. SWOT will measure water elevation over all of the Earth's oceans, lakes, rivers, and wetlands. This will provide a comprehensive picture of the Earth's water resources and how they are changing over time.

3. SWOT will help us understand sea level rise. SWOT will measure sea level change with an accuracy of 1 millimeter (0.04 inches) per year. This will help us understand how the Earth's climate is changing and how sea level rise is affecting coastal communities.

4. SWOT will help us manage water resources. SWOT will provide information on the volume, flow, and storage of water in the Earth's rivers, lakes, and wetlands. This information can be used to manage water resources more effectively and sustainably.

5. SWOT will be launched in 2022. The SWOT satellite is scheduled to be launched in 2022. The mission will last for at least three years, and it will provide data that will be used by scientists, water managers, and policymakers for decades to come.
