Climate model output

Global mean fields described in the 2007 IPCC Fourth Assessment Report (SRES scenarios)

Multi-model ensemble mean surface temperature anomaly

The multi-model ensemble global mean surface temperature anomalies from the IPCC 4th Assessment Report (2007) are available: AR4 global, multi-model means.

Precipitation and surface temperature for each model

Global means for all models are available in text files, combined together into zip archives:

Climate model projections and simulations in the DDC: global gridded fields

Data from individual models can be obtained from the links below. These links also give access to data from earlier IPCC Assessment Reports.

  • Monthly means: monthly mean data for each models and scenario, and a wider range of variables.
  • Climatolgies: 20 and 30 year means for each model and scenario, and a range of variables. Some data is also available in GIS compatible Geotiff format.
