GIFS-TIGGE working group
Currently (until the end of 2014), the The THORPEX GIFS-TIGGE working group coordinates the development, maintenance and exploitation of the THORPEX Interactive Grand Global Ensemble ( TIGGE ) project.
...
The group members include representative from all the TIGGE partners
- Working Group members
- Partners
- Reports from Working Group meetings and workshops
- The TIGGE-LAM project on high-resolution regional ensemble forecasting
Objectives
The THORPEX GIFS-TIGGE working group coordinates two closely-linked aspects of the THORPEX research programme TIGGE and GIFS :

TIGGE panel and PDEF working group
From 2015 (after the end of THORPEX), the TIGGE panel will continue to manage the TIGGE and TIGGE-LAM archives, formalising the current arrangements for coordination between the TIGGE archive centres and data providers. The PDEF (Predictability Dynamics and Ensemble Forecasting) working group will focus on scientific aspects of ensemble forecasting. The TIGGE panel will be represented on the PDEF working group by the TIGGE panel chair, or their deputy.
The panel will be chaired by a representative from a TIGGE archive centre, initially Manuel Fuentes of ECMWF. The membership of the panel are representatives of all the TIGGE and TIGGE-LAM partners:
The full terms of reference for the TIGGE panel are shown below.
TIGGE Panel Terms of Reference (draft, October 2014)
- The panel will secure the technical coordination to ensure the maintenance and continued functionality of TIGGE and TIGGE-LAM archives.
- The TIGGE panel shall comprise representatives from each of the organizations participating in the TIGGE project, either as an archive centre, global or regional data provider, or data processor. Other organizations working on limited-area model ensembles may also be represented on the TIGGE panel on a regional basis.
- The panel will report to the WWRP working group on Predictability, Dynamics and Ensemble Forecasting (PDEF). The TIGGE panel will be represented at PDEF meetings by the panel chair, or their deputy.
- The business of the panel will normally be conducted remotely, via e-mail or other agreed channels.
Objectives:
a) To coordinate the provision of global and regional ensemble prediction data for TIGGE, from data providers to the archive centres and to users.
b) To facilitate communication between TIGGE partners to minimise any disruption in the provision of TIGGE data, including filling any gaps in the data as soon as possible.
c) To keep TIGGE users informed of changes to the TIGGE and TIGGE-LAM archives, including both technical and content changes.
d) To update the PDEF working group with statistical information about usage of the TIGGE and TIGGE-LAM archives, on an annual basis.
e) To implement changes to TIGGE and TIGGE-LAM, as agreed with the PDEF working group in order to support WWRP projects and field experiments.
f) To support the PDEF group in promoting the use of the TIGGE and TIGGE-LAM datasets.
