The ECMWF forecast system IFS was upgraded to the version 49r1. Among other changes, with 49r1, parameters CAPE (59) and CIN (228001) are discontinued and replaced by MUCAPE (228235) and MUCIN (228236). For TIGGE, those new IFS parameters are encoded for consistency still the same as before i.e. with paramId 59 and 228001. More details can be found in TIGGE model upgrades#ECMWF |

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 |
