title27-06-2023 ECMWF forecast system change

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

title10-03-2022 TIGGE portal at CMA

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.
