ASCAT-B
The Advanced Scatterometer (ASCAT) on-board MetOp-B was launched on September 17 2012. ASCAT is operated by EUMETSAT and like its predecessor on ERS-2, operates at a frequency in C-band (5.255 GHz) giving the instrument a near all-weather capability. Six vertically polarised (VV) radar beams, 3 either side of the spacecraft, trace out two 550 km wide swaths separated by a 670 km gap.
ASCAT on Metop-B has been operationally assimilated into the Met Office global forecast model since 30 April 2013.
