OBJECTIVES

Networks for meteorological surface observations are used for a number of applications : weather monitoring and nowcasting , objective analysis for NWP at synoptic scale or sub-synoptic scale, climatology, etc. Through the organisation of a workshop, EUMETNET and MeteoSwiss intend to promote the development of agreed objective methods and tools for the definition of the requirements and the design of these network.
Most of the available information on the subject of usefulness of data addresses profile data from the ground and space, and comes from OSEs, OSSEs and sensitivity studies with data assimilation systems. It is used by the WMO-CBS to establish the global observing systems requirements for upper-air. It is the basis for the proposals by programmes like EUCOS in Europe and NAOS in the USA for the re-design of the radiosonde network.
On the other hand, similar information for surface observation is very limited and even lacking. The definition of the surface component of EUCOS is currently largely open and its is an objective of EUCOS to promote the definition and development of such methods and tools. In parallel, the EUMETNET Members have to consider their requirements for sub-synoptic scale forecasting and climatology in the context of possible EUCOS evolutions.

The "scientific and technical workshop on methods and tools for the design of surface observation network - SWS-2002", in May 2002 will provide an opportunity for network managers and scientists in the application domains (NWP, climatology, etc) to prepare proposals aimed at the establishment of common methodologies and tools..

It is expected that the workshop will provide guidelines for establishing a studies programme to be implemented by the Members and/or in the framework of the EUMETNET programmes (Eg. EUCOS, ECSN, SRNWP), with possible support from other entities. To this respect, participants will be invited to :

 a) review experience gained from the most recent surface network projects implemented by Members, from the point of view of network designers and data users (modellers), and to identify achievements and deficiencies ;
 b) review the available scientific and technical tools applicable to the design of surface networks, such as
  i) construction of fields from point values parameters, as used for forecasting, climatology, etc,
  ii) OSEs, OSSEs,
  iii) statistical evaluation of the information content of networks, etc. ;
 c) propose ideas for a programme of studies and projects.

PROGRAMME

The workshop will be organised in four sessions of three hours each. Three of them will include invited presentations followed by a topic discussion to be summarised by a rapporteur. The last session will include sessions report and a general concluding debate. The preliminary programme below will be finalised by 15 March 2002. Abstracts of registered lectures are now available.
