  4. SWOT capability to observe water height Ohio River SRTM Water elevation measurements In Situ observ-ations from Carlston, 1969; originally by Army Corps of Engineers estimated SWOT Courtesy: Michael Durand, OSU

  5. SWOT capability to estimate discharge Ohio River accuracy estimate based on: Expected SWOT height observation accuracy Temporal sampling errors River width Courtesy: Elizabeth Clark, UW

  6. Height errors and areal errors vary with lake area Height errors dominate Results from Peace Athabasca Delta lakes, Canada SWOT ability to observe storage change Courtesy: Hyongki Lee, OSU

  7. SWOT capability to measure global storage change 25% Analysis based on global lake frequency-area distribution by Downing et al., 2006 10 km x 10 km 1 km x 1 km 250 m x 250 m Courtesy: Sylvain Biancamaria, CNES
