The means and anomalies in the first table below are from the NCEP operational dataset. The operational climatology used to produce the anomalies is based on data from 1985-95. During this period, the assimilating general circulation model underwent many changes. An alternative to the NCEP operational dataset is the NCAR/NCEP Reanalysis dataset which has been produced with an unchanging assimilation model. This data is available about 1.5 months after the operational data.
