Authors Bo Christiansen and Fredrik Charpentier Ljungqvist critically assess the many challenges, including the trade-off between using a larger number of proxy records with a weaker temperature signal and fewer proxy records with a stronger temperature signal, and how the different sources of noise and the complicated covariance structure of the temperature field limit reconstruction skills.
The focus is on single-index reconstructions but some of the observations are also relevant for field reconstructions.
Ljungqvist hopes the paper will illuminate some of the problems related to making large-scale temperature reconstructions from proxy data.
