Altitude rainfall in the Alps

The TPG programme for (Transect of pluviographs for analysis and modelling of Gradients of intensities at altitudes) ran from 1987 to 1995 and then from 1999 to 2004. During these two periods, 28 stations were equipped with pluviographs. The objective of this program was to estimate local peak and slope rainfall quantiles, based on regional results, in order to develop a precipitation model for altitude zones.
The TPG network was established from 1987 in the pre-Alpes du Nord, along an axis joining Lyon (69) to Fond de France (38), thus crossing the Bas-Dauphiné/Chartreuse/Belledonne ensemble, for about 100 km. From 1999, the axis extended to the east (TPG East) in the department of Savoie to encompass the Maurienne valley and the related slopes.
