Nearly 60 participants from 22 different countries in Europe, Asia and the Americas attended the 12th Workshop on Meteorological Operational Systems, which took place at ECMWF from 2 to 6 November 2009.
The focus of the workshop was on observation handling. The workshop reviewed the state of the art and addressed future trends in the role of observations in verification of medium-range forecast products, data management and meteorological visualisations on workstations. The discussion focussed on the challenges to deal with a greater variety of observation types, to handle increasing data volumes and to obtain homogeneous, high-resolution observations for verification. The prospects of exchanging graphical information via web services using international standards were promoted.
