Fennoscandian summers from AD 500: Temperature changes on short and long timescales

Data

• 90_92_Tornetrask.tar.gz contains all the files necessary to run the transfer function and reconstruction

Transfer function (A, B and C refer to the standardisation method given in Table 2)

A - run using first half of chronology (TRW), JA only.

Tree chronology file: booktorn.dat

Climate data file: fennoscandt.dat

To execute the transfer function run: run_tornA_CH.com

BB

Tree chronology file: ttrwfitmxdfit_BB.dat

Climate data file: fennoscandt.dat

To execute the transfer function run: run_tornBB_CH.com

BC

Tree chronology file: tornmxdtrwBC.dat

Climate data file: fennoscandt.dat

To execute the transfer function run: run_tornBC_CH_diff_TRW.com

B - run using first half of chronology (TRW), JA only.

Tree chronology file: tornmxdtrwBB.dat

Climate data file: fennoscandt.dat

To execute the transfer function run: run_tornB_CH.com

The above configurations reproduces the coefficient values in Table 2 of the paper.

Reconstruction

To execute the reconstruction run: run_recon_tornBC_CH.sh which picks up the coefficients file (coeffskBC007.dat) and the parameters file (osrreconBC007.par). The executable used is reconnorm.

The reconstructed series (osrrecon_tsBC007.dat) matches the Table 3 individual years values.
