To assess correction and homogenisation protocols for
early daily instrumental records and produce guidelines
for the quality-assessment, correction and homogenisation
of early instrumental records. To recover data; produce
daily pressure and temperature series for carefully
selected examples from European archives. To characterise
climate variability and determine teleconnection
behaviour across Europe.
Brief Description of the Research Project :
There is a growing interest in climate variability in
Europe, not only because of the "detection" issue, but
also because of the realisation of the importance of the
links between circulation in the North Atlantic Ocean and
climate in Europe.This project intends to describe the
evolution of the climate in Europe and its variability
over the last quarter of a Millenium, by analysis of
hitherto unexploited daily records of air temperature and
pressure from a number of sites across Europe, i.e.
Padova and Milan (Italy), S. Sernando/Cadiz (Spain),
Brussels/Uccle (Belgium), Uppsala and Stockholm (Sweden).
It intends also to augment the newly-produced series with
currently available series (from England, Spain, Czech
Republic, Russia) and publish all data on CD-ROM.
Climatic analysis will include the following: Examination
of high-frequency temperature variability (days-to-seasons) over Europe in order to test the notion of a
decline in high-frequency variability as a response to
anthropogenic influences. Examination of the time-behaviour of the European growing season (very important
for agriculture). Analysis of extreme (high and low)
temperatures (an expected response to anthropogenic
effects). Time-series analysis in order to assess whether
there is any evidence of quasi-regular multi-decadal
oscillations (indicated from ocean model experiments).
Circulation indices over Europe and their relations with
other features of climate variability.
The goals will be reached by means of a close inter-European interaction between specialists in relevant
fields, e.g. historical meteorological instruments and
practices, local climate at the various observation
sites, statistical data analysis, homogeneity testing of
meteorological data series, and climatic analyses in time
and space. The production of the time series will be
undertaken in the most rigorous way devisable through
combinations of expert judgement, use of metadata, and
the application of sophisticated objective techniques.
This will represent a major inter-disciplinary effort,
but the overwhelming priority is to exploit the series to
improve our understanding of the nature and processes of
climate variability and to service the modelling
