This directory contains all time series data show in MBH98 figures.

Included are:

1. Figure 5a ('nhmean.dat')

Northern Hemisphere (NH) annual mean temperature reconstruction and 
uncertainties, and instrumental NH series in format: Year (column #1), 
Reconstructed annual Northern Hemisphere mean temperature reconstruction 
temperature 1400-1980 (column #2), instrumental NH series 1902-1995 
(column #3), and +/- 1 and 2 sigma uncertainty intervals (columns #4-7).

2. Figure 5b ('rpc01.dat','rpc02.dat','rpc03.dat','rpc04.dat','rpc05.dat')

Reconstructed Principal Components (RPCS) #1-#5 in format: Year (column #1), 
Reconstructed Principal Component (column #2)

3. Figure 7 data:

'fig7-nh.dat': Reconstructed annual Northern Hemisphere mean temperature 
series back to 1610. Note that this version is slightly different
from that shown in Figure 5a of MBH98. That figure was based on an
older version of the reconstruction, which the authors did not update 
in the final version of the manuscript. However, there are no 
significant differences from that shown in MBH98 Figure 5a.

 
'fig7-solar.dat': solar irradiance series of Lean et al (1995) which is 
   available back to AD 1610
'fig7-co2.dat': spliced ice core/instrumental co2 data back to AD 1610
'fig7-dvi.dat': volcanic Dust Veil Index (DVI) series back to AD 1610.
'fig7-corrs.dat': moving correlations with forcings, and confidence levels 
   for significance as determined from resampling. There are 7 columns: 
   Column 1 is year, column 2 is co2 partial correlation, column 3 is solar 
   partial correlation, column 4 is volcanism partial correlation, and columns 
   5,6,7 are one-sided positive  90%,95%,99% confidence intervals for co2 
   (the values for solar are nearly identical). Volcanic forcing has lower 
   conf thresholds as noted in paper. The one-sided (negative) confidence 
   intervals are: 90% = -0.13, 95% = -0.16, 99% = -0.21
