The Wattisham Radian LAP3000 is permanently located at an existing Met Office at RAF Wattisham. This system is an integral part of the UK operational upper air network. Wattisham, like the other UK sites, is configured to operate in two modes. The low mode provides high resolution wind information up to 2km above the surface, while the high mode, with 210m resolution can see up to 8km under appropriate conditions.
