New version of ECMWF IFS model (cycle 48r1) has been introduced at ECMWF since 6Z run on 2023-06-27. With IFS Cycle 48r1, the horizontal resolution of the medium-range ensemble (ENS) will increase from 18 to 9 km. This will bring the ENS to the same horizontal resolution as the high resolution forecast (HRES). The vertical resolution for both ENS and HRES will remain at 137 model levels and the ENS will continue to have 51 members. For TIGGE, the IFS data is interpolated to the same resolution O640 as up to now. More details can be found in TIGGE model upgrades#ECMWF |

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://www.cawcr.gov.au/research/cyclone-exchange/ 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. 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 |

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. |

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. |
