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 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.

The upgrade will bring more accurate upper air fields, particularly tropical winds, as well as precipitation in convective regimes. Several new convection-related products will be available and systematic errors are reduced for wind gusts and visibility for fog and precipitation
