The TIGGE archive consists of ensemble forecast data from eleven thirteen global numerical weather prediction (NWP) centres, starting from October 2006.
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. Further information is available from this leaflet, the web page on GIFS (Global Interactive Forecast System) and on other pages of this website.
We anticipate that TIGGE, together with TIGGE-LAM, will provide valuable data to support both the Polar Prediction Project (PPP) and High-Impact Weather (HIWeather) project, as well as other WWRP projects. The third THORPEX legacy project on Subseasonal to Seasonal Prediction (S2S) has its own archive dataset.
We request researchers using TIGGE to inform us of their research progress, particularly when papers are published.
