If you require NCEP predictor variables for the period 1948 to 2017 you should email c.w.dawson1@lboro.ac.uk with the filename you require. The filename is case sensitive and should include the full name including the extension - for example, BOX_12.5N_132.5E.zip. I can only provide one or two files per request.

To determine the filename you require you can use the Excel spreadsheet calculator available here. Enter your desired coordinates and it will determine the name of the file you should request (for example, BOX_12.5N_132.5E.zip).

Note: No GCM predictors are needed for SDSM-DC.
