Workshop on Assimilation of high spectral resolution sounders in NWP

The workshop on Assimilation of high spectral resolution sounders in NWP was held from June 28 to 1 July.

Description

The NASA AQUA satellite was successfully launched in May 2002 and sampled radiance data from the AIRS (and the accompanying AMSU-A) instruments are now available in near-real-time (NRT) to the NWP community. Most NWP centres have undertaken major research and development efforts for the validation and assimilation of this new advanced infrared sounder.

The aim of the workshop was to review the critical issues related to the assimilation of high spectral resolution sounders in operational NWP centres, in particular monitoring, cloud detection, channel selection, data compression and radiative transfer modelling.
