  • GISP2 (note that the age model has been updated)
  • National Geophysical Data Center (NGDC)

Paleo Reconstructions (including code)

  • Reconstructions index and data (NOAA)

  • Kaufmann et al (2009)
  • Wahl and Ammann (2006)
  • Mann et al (1998/1999)

Large-scale model (Reanalysis) output

These are weather models which have the real world observations assimilated into the solution to provide a ‘best guess’ of the evolution of weather over time (although pre-satellite era estimates (before 1979) are less accurate).

  • ERA40 (1957-2001, from ECMWF)
  • ERA-Interim (1989 – present, ECMWF’s latest project)
  • NCEP (1948-present, NOAA), NCEP-2
  • MERRA NASA GSFC
  • JRA-25 (1979-2004, Japanese Met. Agency)
  • North American Regional Reanalysis (NARR)
  • 20th Century Reanalysis (1871-2008)

Large-scale model (GCM) output

These is output from the large scale global models used to assess climate change in the past, and make projections for the future. Some of this output is also available via the Data Visualisation tools linked below.

  • CMIP3 output (~20 models, as used by IPCC AR4) at PCMDI
  • GISS ModelE output (includes AR4 output as well as more specific experiments)
  • GFDL Model output

Model codes (GCMs)

Downloadable codes for some of the GCMs.

  • GISS ModelE (AR4 version, current snapshot)
  • NCAR CESM; NCAR CCSM(Version 3.0, CCM3 (older vintage))
  • EdGCM Windows based version of an older GISS model.
  • Uni. Hamburg (SAM, PUMA and PLASIM)
  • NEMO Ocean Model
  • GFDL Models
  • MIT GCM
  • DOE E3SM

Model codes (other)

This category include links to analysis tools, simpler models or models focussed on more specific issues.

  • Radiative Transfer models (AER RRTM)
  • Rahmstorf (2007) Sea Level Rise Code
  • Vermeer & Rahmstorf (2009) Sea Level Rise Code and Data
  • ModTran (atmospheric radiation calculations and visualisations)
