From the 06UTC forecast on 21st October 2015, the Met Office tropical cyclone prediction (CXML) data is now based on the higher-resolution MOGREPS-G forecasts. MOGREPS-G is run four times a day (00, 06, 12 and 18Z) using a 12-member ensemble with a grid length of approx 33km. Until now, the CXML data was based on the lower resolution MOGREPS-15 ensemble, even though MOGREPS-G data has been supplied to the TIGGE archive since July 2014. Note that each CXML dataset includes tracks from a lagged ensemble of 24 members, i.e., the current forecast and the forecast from 6 hours earlier. The CXML data are available via the NCAR archive at http://rda.ucar.edu/datasets/ds330.3/ or see the TIGGE cyclone exchange page at http://cawcr.gov.au/projects/THORPEX/TC/index.html for further information. |

The Met Office TIGGE data now includes data from the higher resolution, 7-day MOGREPS-G global ensemble (rather than MOGREPS-15, as used up to 00Z 15th July). The new data are being provided in near-real time from 00Z 6th November, and it is planned to back-fill the gap in due course. The new ensemble data includes 12 members run four times a day, with a reduced number of parameters. See attachment below Click here for more details. |

From Tuesday 15th July, the 15-day MOGREPS-15 EPS data will no longer be sent to TIGGE. It will be replaced by higher resolution MOGREPS-G data, with a 7-day range. There will be a gap in the data provision, but it is planned to back-fill the missing data within a few weeks. The number of TIGGE parameters available from the new MOGREPS-G feed will be significantly reduced. See attached file Click here for more details. |

A recent review of the NCEP TIGGE data has shown that there were errors in the five time-integrated energy flux fields: outgoing long wave radiation, surface latent heat flux, surface net thermal radiation, top net solar radiation and surface sensible heat flux. The data have been corrected from 9th April 2014, but unfortunately it is not feasible to correct past data. Thanks to NCDC, who post-process twelve of the NCEP TIGGE parameters, for indentifying and correcting the problem. For furthe ... more |

A new version of ECMWF model was introduced at ECMWF. Parameter convective inhibition (CIN) has been added to the TIGGE database. |

JMA have reported that the current 'Land-sea mask' values in the JMA TIGGE data are incorrect. Although the land-sea mask has not changed, an error in output processing resulted in incorrect land-sea mask data starting from 16 December 2010. Data before that date is correct. JMA are working to both fix the problem and improve their EPS within a few months, and will make further announcement when the changes have been made. |

A representation of model uncertainty was introduced into the medium-range EPS from the Japan Meteorological Agency (JMA) on 17 December 2010. The method uses a stochastic perturbation of the physical tendencies. |

The ensemble forecasts from the Australian Bureau of Meteorology's GASP EPS have been terminated from 20th July 2010, and so are no longer being input to the TIGGE data base. A new system, AGREPS (an Australian implementation of the Met Office MOGREPS system) is under development. In due course AGREPS data will be included in TIGGE, but it is anticipated that there could be a gap of a year or more before AGREPS is operational. |

We are currently updating this website. We have added more information about TIGGE research and the GIFS-TIGGE working group, and links to several other TIGGE-related websites. Further changes will follow soon - specifically changes to the dynamic web pages (the ones with "/d/" in their URL) to make them consistent with the rest of the website. Richard Swinbank. |

JMA will update the distribution scheme of JMAs EPS data for TIGGE data base on 20 March 2007 from ftp-put by JMA to http-get by ECMWF from our new data distribution server.
Furthermore the forecast-step interval of all pressure level parameters and surface pressure was changed from 12 hours to 6 hours. The land-sea mask and orography for control forecast at forecast-step 0 were also added. |

UK MetOffice added total column water, soil moisture (with wilting point & field capacity in control run output) and soil temperature to the TIGGE database. Furthermore wind (u and v) was added on potential vorticity level 2 PVU. The Land Sea Mask for control forecast at all timesteps is now also available from the UK MetOffice. |

ECMWF implements Variable Resolution Ensemble Prediction System and extends the forecast range from 10 days to 15 days. The forecast consists of two legs: leg 1 goes from day 0 to day 10 and is followed by leg 2 going up to day 15. The Atmospheric Model runs at resolution T399 (62 vertical levels) or N200 for leg 1. Leg 2 runs at resolution T255 (62 vertical levels) or N128. This change is carried over to the TIGGE Database. |
