The data are from Chapman, W. L. and J. E. Walsh, Long-Range Prediction of Regional Sea Ice Anomalies in the Arctic, Weather and Forecasting, 6, pp 271-288, 1991. The data are available from the The National Snow and Ice Data Center. The only changes at this point are that the fields have been interpolated onto the NCEP sea ice grid. The NCEP grid is more extensive, so that there are zones which report no ice cover.
