The new IFS Cycle 47r3, expected to be the last upgrade before ECMWF's new data centre in Bologna will become operational, is scheduled to be implemented on 5 12 October 2021.

IFS Cycle 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.
