*Abstract*

The presentation will summarize some of the key updates of the ECMWF model
and data assimilation systems over the past 2 years, after a brief
introduction of ECMWF and its forecasting framework. Three examples of
system upgrades will be given, namely the introduction of the ensemble of
data assimilations, the revision of microwave sounder observation errors,
and the new prognostic cloud scheme. Their respective impact on analysis
and forecast skill will be demonstrated as well as the difficult trade-off
between objective system improvements and positive impact on skill.
Finally, the importance of observation monitoring in data assimilation will
be highlighted with two examples.
