ECMWF's Operational Model Analysis, starting in 2011

European Center for Medium-Range Weather Forecasts (ECMWF) atmospheric operational model analyses and products derived from short-term forecasts. These data are archived at the highest resolution of the data assimilation and forecast system. The free atmospheric data are on constant pressure surfaces and there are many surface fields, single level integrated fields, and boundary layer fields. This dataset is an extension of the older and lower resolution ECMWF operational output datasets in the NCAR Research Data Archive.
