Starting on June 15, 2021, some of the S-band radars have a modification of the scanning strategy : a low level angle of 0.3 degree will use a low PRF to extend its range to 400 km in reflectivity while a mid-level angle will be eliminated in the cycle in order to help in radar coverage.
English: A schematic of the water surface level changes with the tides. Average low water spring or average low water neap tide; used as a reference, which one is used depends on whether LWN or LWS is lowest. The schematic was hand drawn based on an image from the book "Leidraad voor het Stuurbrevet" by Richard Vooren, Paul Van den Keybus.
