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 MBH98 Figure 5; it was based on a an older version of the 
reconstruction, which the authors forgot to update in the final version of 
the manuscript. There are know significant differences, however,from that 
shown in 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
