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 |

After the KMA model update on 1th of July 2022,the values of Surface net solar radiation were wrong . Also there were some occasional unwanted zero values for some other parameters (2t, 2d, tcc, 10m u/v etc). The affected data has been fixed now. Find more information in Issues with data. |

The TIGGE portal at CMA should be available now again after a while in http://tigge.cma.cn/ It should contain in principle the same data as the TIGGE archive at ECMWF. Currently after some technical issues in the past, the data is still available only for more recent period which should be extended soon to contain more historical data too. |

New version of ECMWF IFS model (cycle 47r3) has been introduced at ECMWF since 6Z run on 2021-10-12. Cycle upgrade 47r3 will bring improvements to the assimilation and observations usage and a significantly improved physical basis for moist processes, necessary to facilitate further development of the Integrated Forecasting System (IFS) and future application at convection-permitting resolutions.

New version of ECMWF IFS model (cycle 47r2) has been introduced at ECMWF since 2021-05-11. In the IFS Cycle 47r2 single-precision for ENS (forecast up to day 46 and hindcast) and HRES (forecast) has been introduced. Moreover, the ENS vertical levels has been increased to 137 to bring it in line with HRES. This change will not affect the format of TIGGE products from IFS.

The horizontal resolution of t he ECCC contribution to TIGGE has been increased from 1.0 to 0.25 degree since 12Z Also the GRIB 2 packing has been changed to simple instead of complex one (that will generally increase file sizes but also significantly reduce time needed to process such data). All TIGGE data from all participating models should be encoded now using simple GRIB 2 packing. Further details can be found in the page Models . |

The outputs from the global model ICON produced by Deutscher Wetterdienst (DWD) have been added to TIGGE archive starting from 12Z, 7 December 2020. In contrary to other ensemble systems, in ICON the control forecast is not produced (the ensemble consists of 40 perturbed members only). The high resolution forecast interpolated to the same resolution as the ensemble is also available for users. Click here for more details. |
