QuikSCAT SeaWinds Ocean Surface Winds
QuikSCAT SeaWinds ocean surface winds depict wind velocities at an elevation of 10m. The strictest rain flag has been used to yield wind speeds within 2m/s.
- Presented wind speed and direction values should not be considered absolute
- In storms with high wind gradients, the wind speed values will be underestimated
- Rain flags in use will not necessarily detect all precipitation events
- Data buffer is 22 hours prior to the most recent update time.
Products are updated at 03:00, 06:00, 09:00, 12:00, 15:00, 18:00, 21:00 and 24:00 GMT.

The current empirically derived model function being used to relate normalized radar cross-section
with wind speed and direction is referred to as QSCAT1. The strictest Multidimensional Histogram (MUDH)flag has been used to yield
wind speeds within 2m/s.
