Updates and errata

Updates:

  • update.131030.pdf Temperature reconstruction by domain: preliminary analysis
    Further work on geographical variations between the surface and satellite data and preliminary results from reconstruction of the separate land and ocean data. The code is already in the distributed coverage.zip file.
  • update.140106.pdf Temperature reconstruction by domain: version 2.0 temperature series
    Description of a new temperature reconstruction running from 1850 to the present based on separate global reconstructions of the HadCRUT4 land and ocean ensembles.
  • update.140205.pdf Hybrid temperature reconstruction by domain
    Description of six new satellite era temperature reconstructions runnings from 1979 to the present based on separate global reconstructions of the HadCRUT4 land and ocean ensembles and GHCNMv3 land data, by kriging and hybrid with UAH satellite and MERRA reanalysis data.
  • update.140404.pdf Reconciling temperature series
    An investigation into why our temperature trends are higher than those for GISTEMP.

  • gleisner-response.pdf Response to Gleisner et al. (2015)
    A response to a paper in GRL which failed to reproduce our results (code). Compare with Simmons and Poli (2014).

As of 2014-04-21 subtitles have been added to each of the update documents to make them easier to reference.
