SRNWP EXPERT TEAMS (ET):
DEFINITION and TERMS OF REFERENCES

During the last SRNWP business meeting (Dubrovnik, 11^th of October, 2007), the creation of the following Expert Teams was proposed (listed below in alphabetic order together with some hints of their content):

1. Data assimilation and use of observations
• Data assimilation methods, algorithmic choices, application of new observation types, OSE and OSSE experiments, ensemble data assimilation
2. Diagnostics, validation and verification
• Data pre-processing, validation and inter-comparison of models
• Verification Programme to be prepared (updated)
3. Dynamics and lateral boundary coupling
• High resolution numerics, numerical techniques, new methods for LBC coupling
4. Link with applications
• Two-way interaction between various downstream applications (hydrology, environment, aviation, oceanography), statistical adaptation
5. Physical parameterisation (upper air)
• Parameterisation schemes, high resolution numerics, PBL-surface interaction
6. Predictability and EPS
• Predictability issues, addressing uncertainties in the NWP models, LAMEPS, ensemble data assimilation
• EUREPS Programme to be updated
7. Surface and soil processes (model and data assimilation)
• Physiographic data, PBL-surface interaction, modelling and DA techniques for continental surfaces and upper ocean layers
8. System aspects
• Data pre- and post-processing, code aspects
• Interoperability Programme to be submitted to the EUMETNET Council

For the time being the SRNWP Advisory Committee will deal with the issues related to the socio-economic benefits of the NWP models and also considers the client-oriented verification.

Terms of references of the Expert Teams

The "Terms of references (ToR)" below gives a guideline to the Expert Teams to start their work. The Expert Teams have the right and possibility to comment and amend the ToR below and they are asked to prepare their workplan.

Organisation:

1. The core of the Expert Team is the 5 contact points from each LAM Consortia (ALADIN, COSMO, HIRLAM, LACE, MetOffice).
2. The Expert Team elects its chairperson among the Consortia contact points.
3. The Expert Team chairperson is the main initiator of the activities of the Expert Team and makes liaison towards the SRNWP Programme Manager.
4. The Expert Teams should be sufficiently "large-spread" in order to cover sufficient expertise.
5. Young scientists should be also members of the Expert Teams.
6. The basis of the work of the Expert Teams is the annual workplan to be agreed by the Team itself and surveyed by the SRNWP Advisory Committee.
7. Most of the work of the Expert Teams are realised through email exchanges, but if needed, meetings can be organised (beside the workshops).

Duties:

1. Supervise the programmes (EUMETNET supported ones and "cooperative" programmes not supported financially by EUMETNET) belonging to their expertise.
2. Organise their work in order to optimise the share of the work between the LAM Consortia.
3. Foster exchange of technical and scientific ideas and expertise.
4. Support training activities.
5. Organise (or co-organise with other ETs) workshops regularly (typically once per two-years), where beside SRNWP members scientists from outside Europe and from the academic institutions (and universities) might be invited.
6. Give expertise towards other EUMETNET Programmes (if needed).
7. Prepare reports to the SRNWP Advisory Committee and to the SRNWP Programme Manager
8. On cross-cutting issues liaise with the other Expert Teams.

Actions needed

1. Approve (amend, modify) this document; as soon as possible by the Consortia heads
2. Nomination of contacts to each Expert Team, deadline: end of November
3. Election of chairpersons of the Expert Teams, deadline: end of December
4. Compilation of annual workplan (with plan of actions) for the Expert Teams, deadline: end of February
