ASCAT-A

ASCAT-A

The Advanced Scatterometer (ASCAT) was launched by the European Space Agency (ESA) aboard the MetOp-A satellite on October 19, 2006. 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. This provides a higher resolution and twice the coverage of the AMI instrument on ERS-2.

ASCAT has been operationally assimilated into the Met Office global and regional forecast models since 17 November 2007.
