Abstract
Operational data from 1st January 2002 to present containing the ongoing analyses and forecasts produced by the most recent ECMWF Integrated Forecasting System (IFS) model. Data are available at the resolutions used for the ERA 40 reanalysis project - i.e. reduced Gaussian N80 for surface data and spectral T159 for upper air data. The IFS is regularly updated as improvements are made to the model, computing facilities and observations used in data assimilation.
