Tree chronology file: booktorn.dat

Climate data file: fennoscandt.dat

To execute the transfer function run: run_tornAA_CH.com

The above configuration reproduces the values in Table 2 of the paper.

Reconstruction

To execute the reconstruction run: run_recon_tornAA_CH.sh which picks up the coefficients file (coeffskAA997.dat) and the parameters file (osrreconAA997.par). The executable used is 'reconnorm'.

The reconstructed series (osrrecon_tsAA997.dat) matches the values in Table 3 'Individual Summers'.
