The Effective Atmospheric Angular Momentum (EAAM) is a combined project from the Met Office and the European Centre for Medium Range Weather Forecasting (ECMWF). The data is of 3 angular momentum components of the mass and wind terms at 12 or 24 hourly intervals. The ECMWF data are from 1979-93. The corresponding Met Office Unified Model data cover the period from 1983 to 1997. This dataset is public.
