Summary
Abstract: These two files contain the Graduated Indices GI [+3 ,-3] for both temperature
and precipitation from 1525 to 1989. The first column contains the year,
followed by the monthly temperature indices. Then there are five columns with
indices for each season and the year. Precipitation indices are provided in
the same order.

The Graduated Index GI [+3,-3] is bound on a high density of data and on the
availability of quasi continuous proxy data from historical and natural
archives that are calibrated within the period of instrumental observations.
The reference period is 1901-1960. Winter temperatures are estimated from
hydrological indicators such as the proportion of the number of snowfalls
relative to that of rainy days, the duration of snow-cover and the freezing of
lakes in the Alpine borderland and observed signs of vegetative activity. For
the spring and summer season the focus is on biological indicators such as
dendro-climatic data, phenological observations, para-phenological indicators
such as grape or vine harvest dates, as well as on continuous quantitative
data on the volume of vine harvests, but also on snow-falls in the Alps.
Precipitation is estimated from the number of rainy days obtained from weather
diaries and from evidence on floods and low water tables of large rivers and
lakes.

Monthly, seasonal and yearly indices may take the following values:
+ /3 for very warm or wet, cold or dry anomalies respectively.
Anomalies are defined as <1st duodecile or >11th duodecile
according to the 1901-60 distribution for temperature.
The precipitation index is based upon several instrumental
series of both sums of precipitation and number of days with
precipitation >0.3mm (see Pfister 1984 for details)
+ /-2 for warm or wet, cold or dry months, respectively
+ /-1 for months with temperature or precipitation above or below average
0 for "average" months or data not available

On a seasonal level the GI is defined as the average of the monthly GI, which
yields gradations of 0.3 between -3 and +3. Anomalies correspond to graduated
indices of >= + 2.3 and <=- 2.3, respectively. On a yearly level the GI is
defined as the average of the monthly GI.

The entire documentation which underlies the indices is titled CLIMHIST-CH, and
is available on paper or microfiche from METEOTEST, Fabrikstr. 29 a, CH 3012
Bern Switzerland.
