Find general information about the TIGGE archive below or follow other links in this section to the detailed information about archived parameters, participating models and operational archiving suite.
General information
The TIGGE archive consists of ensemble forecast data from ten global NWP centres, starting from October 2006, which has been made available for scientific research. TIGGE has become a focal point for a range of research projects, including research on ensemble forecasting, predictability and the development of products to improve the prediction of severe weather. The TIGGE project is overseen by the GIFS-TIGGE working group, which includes representative of the TIGGE data providers and the TIGGE archive centres. Further information is available from this leaflet and on other pages of this website. We encourage researchers using TIGGE to inform the GIFS-TIGGE working group of their research progress, particularly when papers are published.
This page provides links to a wide range of documentation and software tools for the TIGGE project.
