ESURFMAR Report to DBCP

ESURFMAR Report to DBCP by Jean Rolland, Pierre Blouch, Michel Trémant DBCP 23 -Jeju 15-19 October

ESURFMAR E-SURFMAR is an optional programme of the ground based EUMETNET Composite Observing System (EUCOS) EUMETNET is the Conference of European National Meteorological Services (22 WMO members in 2007) Météo-France is the EUMETNET member responsible for E-SURFMAR

E-SURFMAR Programme Main Objectives EUMETNET meets 22 European Meteorological Services. Austria, Belgium, Croatia, Cyprus, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Ireland, Latvia, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom 17 out of them are participating in E-SURFMAR To co-ordinate, optimise and progressively integrate the activities for surface marine observations within the EUCOS Operational framework Main EUCOS aim : to optimise the ground observing system to improve Numerical Weather Prediction (NWP) over Europe First stage 2003-2006 New phase 2007-2011

E-SURFMAR Area
