|T/P flies in a groundtrack that repeats every 10-days and goes as far north and south as 66o latitude. This means that it samples approximately 400,000 points over the ocean every 10-days. Compare that to ship measurements, moored buoys, or tide gauges. However, there are still gaps in the data, which means that the image on the earlier slide is based on interpolating real measurements to a constant grid, then smoothing them and plotting them graphically and assigning colors based on the heights.|
| Lines are the T/P groudntrack and |
dots are locations with more than
24 ship measurements in 3 years.
