With more and more pseudoproxy experiments emerging in the literature it seems a useful point in time to review where to get the data for performing these experiments.  More resources are emerging as increasing numbers of millennial simulations become available and as various flavors of pseudoproxy experiments emerge.  This post will try to review what is available online and what is likely to become available over the next year or so.

Regarding basic output from millennial simulations (on which pseudoproxy experiments are typically based), several fields are available publicly.  You can find the complete surface temperature fields for the NCAR CCSM1.4 (Ammann et al. 2007) and ECHO-G ERIK1 (Gonzalez-Rouco et al. 2003) millennial simulations online here.  Note that these fields were subject to processing errors (pdf) in earlier pseudoproxy studies, and that both the corrected and incorrect fields are given at the above data link for reference.  Masked versions of the surface temperature field from the CCSM1.4 and the updated ECHO-G ERIK2 (Gonzalez-Rouco et al. 2006) millennial simulations are also available here.  While others are not necessarily public, there are a handful of other millennial simulations that were most recently described here (pdf).  These simulations are typically available through requests to the lead authors of the principal studies.  More millennial simulations are also coming online over the next year as part of phase 5 of the Coupled Model Intercomparison Project (CMIP5) and will greatly increase the number of these publicly available simulations.

For pseudoproxy networks, there are also a few resources available online.  You can find temperature and temperature+noise pseudoproxy networks approximating the Mann et al. (1998 and 2008) networks here.  A great new resource is also available through NOAA’s Paleoclimatology website providing new pseudoproxy data that approximate the Esper et al. (2002) and D’Arrigo et al. (2006) proxy networks.  Note that in addition to the CCSM1.4 and ECHO-G ERIK2 simulations, these frameworks also have been constructed using output from a millennial run of the Max-Plank Institute Earth System Model.

Reconstruction codes are also becoming more widely available.  Codes for multiple methods are publicly available as listed below.

The above should be fairly comprehensive as of the writing of this post.  I will try to update as appropriate and please let me know if I have unintentionally missed a good resource.
