GEOGRAPHIC REGION: Global
PERIOD OF RECORD: 100 B.C. - 1990 A.D.
LIST OF FILES: 13 files, see description below.

DESCRIPTION:

File 1: ch1.txt: Tables 2.1 and 2.2, Annual indices of summer ice 
severity in eastern and western Hudson Bay, plus  data from Hudson 
Strait, and thermal indices for the southeast coast of Hudson Bay.

File 2: ch6.txt: From C. Pfister.  Monthly temperature and 
Precipitation indices (Figure 6.4).

File 3: ch11.txt: Data from W.C. Wang et al.  Number of rain 
days, daytime rain hours, and night-time rain hours from the Qing-Yu-
Lu for May, June and July, 1724-1903.

File 4: ch13.txt: Data from Jones and Bradley.  Monthly 
temperature and precipitation data from some of the long-term stations 
shown in Figures 13.1 and 13.2.  Also seasonal and annual 
temperature anomalies (from 1951-70) averages for northern and 
southern hemisphere land areas ( Figures 13.3 and 13.4) and for 
COADS SST data for the northern and southern hemispheres (Figure 13.5).

File 5: ch15.txt (north_namerica.dat): data from D'Arrigo and Jacoby.  
Reconstructed mean annual temperatures for northern North America, from Figure 
15.4.  (Note:  captions for Figs. 15.3 and 15.4 are reversed in the book).

File 6:  ch16.txt (usa_regions.dat):  from Meko.  Standardized regional tree- ring 
series for regions 0 to 9 (Figure 16.1) and scores of the first three 
eigenvectors from PCA on regional tree-ring series, 1750-1964 (Figure 16.3).

File 7: ch17.txt (east_usa_pdsi.dat): data from Cook et al.  Obliquely rotated 
drought factor scores based on 23 PDSI reconstructions for the eastern United 
States (shown in Figure 17.3).

File 8: ch19.txt (north_sweden.dat): data from Briffa and Schweingruber.  
Ring width chronologies for several sites around Lake Inari (northern Finland) 
and the Tornetrask region of northern Sweden (shown in Figure 19.2).  
Also contains data from Figures 19.4 and 19.7.

File 9: ch20.txt (nw_russia.dat): data from Graybill and Shiyatov.  
Reconstructed June-July average temperatures at 65N, 70E (N.W. Russia) 
expressed as departures from the 1951-70 average ( Figure 20.4).

File 10: ch23.txt (chile.dat): data from Boninsegna.  Data on reconstructed: 
winter precipitation at Santiago de Chile; summer and winter 
anticyclone positions and summer precipitation at Chiloe ( Figure 
23.2); summer temperatures in northern and central Patagonia (Rio 
Alerce) and indices of summer temperature at Ushuaia (shown in 
Figure 23.3); streamflows of Rivers Atuel, Neuquen and Limay (Figure 23.4).

File 11: ch24.txt (newzealand.dat): data from Norton and Palmer.  R reconstructed 
climate and riverflow data for New Zealand (shown in Figures 24.4 and 24.5).

File 12: ch25.txt: data from Holdsworth et al.  Mount Logan 
oxygen isotope (delta O-18) and net accumulation data (meters of 
water equivalent, per year) ( Figures 25.3 and 25.4).  Note: The title of 
this chapter should read: "Ice core climate signals from Mount Logan, 
Yukon, A.D. 1700-1987" (not 1897).

Svalbard (shown in Figures 26.6 and 26.7).

File 14: ch32.txt: data Quinn and Neal, historical El Nino record
from Table 32.1.
