Description
This picture shows the scatterometer winds (in arrows or flags), with an infrared satellite image (from METEOSAT, GOES or Himawari).A wind flag is represented by barbs and solid pennants, a full barb representing a wind speed of 5 m/s, a half barb representing a wind speed of 2.5 m/s, and a pennant representing a wind speed of 25 m/s. A calm indicator circle is plotted if the wind speed is less than 0.5 m/s.
The exact data acquisition time is plotted in red next to the satellite swath.
A magenta marker on top of the wind arrow denotes land or ice presence. Orange wind arrows or flags indicate that the Variational Quality Control flag is set, i.e. the Wind Vector Cell is spatially inconsistent. Black arrows or flags mean that the KNMI Quality Control Flag is set. More information on the quality flags can be obtained from the Product User Manual.
Note that in the detail pictures, the scatterometer winds are plotted on a cell spacing of 25 km, i.e. only a quarter of the wind vectors is plotted. In some regions however, also a full resolution picture showing all wind vectors is available by clicking on the detail picture.
