Download: GCM Outputs

All the GCM outputs are model hindcasts and real-time forecasts, and so are meant for use in predictive analyses and forecasting (there are no AMIP-type outputs, for example). Access is provided to outputs from five of the National Multi-Model Ensemble (NMME) members, and to one two-tiered forecast system:
  • CFSv2: a one-tiered system, with hindcasts starting in January 1982. This model is part of the National Multi-Model Ensemble.
  • ECHAM4.5: a two-tiered system using constructed-analogue SST forecasts as boundary forcing, and with hindcasts starting in January 1957. (Note these model outputs were discontinued in 2017).
  • CMC4: a one-tiered system, with hindcasts starting in January 1981. (Note that there is a gap in the data: outputs for start dates between January and November 2011 are unavailable. CPT will recognise the gap so the only thing to consider is the Maximum % of missing gridpoints/stations/values.) This model is part of the National Multi-Model Ensemble.
  • COLA RSMAS CCSM4: a one-tiered system, with hindcasts starting in January 1982. This model is part of the National Multi-Model Ensemble.
  • GFDL FLOR B01: a one-tiered system, with hindcasts starting in March 1980. This model is part of the National Multi-Model Ensemble.
  • NCAR CESM1: a one-tiered system, with hindcasts starting in January 1980. (Note that there is a gap in the data: outputs for start dates between January 2011 and June 2016 are unavailable. CPT will recognise the gap so the only thing to consider is the Maximum % of missing gridpoints/stations/values.) This model is part of the National Multi-Model Ensemble.
If multiple pressure levels are selected, CPT will read these as multiple fields. Otherwise, to combine predictors and / or models, first download the individual files and then use the Data ~ Merge option. The data are typically updated towards the end of the first week of each month.
