Testing the Fidelity of Climate Reconstruction Methods

Two methods of different complexity are compared

Proxy ReconstructionsMann et al., in a recently published paper, reconstructed past climate histories using the two most common techiques for processing "proxy" climate data. Climate Field Reconstruction (CFR, well suited for spatial patterns) and Composite-Plus-Scale (CPS, with a simpler statistical procedure) methods are used in this study. Results are tested for long-term fidelity against climate model simulations.
