Training session on homogenisation methods


(Bologna 17-18 May, 2005)

 


Training Program Application Form Practical Information List of Participants Contributions Photos

In the last decade the scientific community has become increasingly aware of the fact that the real climate signal in original series of meteorological data generally lies hidden behind non-climatic noise caused by station relocation, changes in instruments and instrument screens, changes in observation times, observers, and observing routines, algorithms for the calculation of means, and so on. So at present time the statement that time series of meteorological data cannot be used for climate research without a clear knowledge about the state of the data in terms of homogeneity has a very large consent.
There are different ways for solving homogeneity problems, and the choice of the most suitable one not only depends on the data-set characteristics (metadata availability, station density, and so on), but is also influenced by the homogenisation "philosophy" adopted by the research group that performs homogenisation.

Within this context, in the frame of the activities to be performed within the INTERREG IIIB Alpine Space Project FORALPS, ISAC-CNR has organised a training session aiming to explain its approach toward the use of homogenisation methods for the analysis of time series of meteorological data. Homogeneity tests, methods, limits and benefits of homogenizing meteorological records will be discussed, and a demonstration of the homogenisation of real time series will be given. The training session is also addressed to absolute beginners.
The training session will be held Tuesday 17th to Wednesday 18th May 2005 at the Istituto di Scienze dell'Atmosfera e del Clima (ISAC, Institute for Atmospheric and Climate Sciences) of the Consiglio Nazionale delle Ricerche (CNR, National Council for Research) in Bologna, Italy. The teachers will be Maurizio Maugeri (Milan University) and Michele Brunetti (ISAC CNR).

There are 25 places available on the training session: the deadline for applications is Friday 29th April 2005. No fee is required.
