Comparison of scores between IFS Cycle 43r1 and IFS Cycle 41r2 for HRES can be found in the IFS Cycle 43r1scorecard.
Upper air
The new model cycle provides improved high-resolution forecasts (HRES) and ensemble forecasts (ENS) throughout the troposphere and lower stratosphere. In the extra-tropics, error reductions of the order of 0.5-1% are found for most upper-air parameters and levels. The improvement in the primary headline score for the HRES (lead time at which the 500 hPa geopotential anomaly correlation drops below 80%) is about 1 h.

Users of the dissemination wishing to continue using three-hourly accumulations are advised to change their requirements to request 10FG3, MX2T3, MN2T3, MXTPR3 and MNTPR3 (as replacement for the current 10FG, MX2T, MN2T, MXTPR, MNTPR). Alternatively they can contact Dragan Jokic (Member and Cooperating States) or Data Services (Commercial customers). Users accessing these data via MARS should change their requests in the same way. They can also contact ECMWF User Support . |
