Sažetak
The paper describes the development of a dataset of 192 monthly precipitation series covering the Greater Alpine Region (GAR, 4-18&ordm ; ; E by 43-49&ordm ; ; N). A few of the times series extend back to 1800. A description is provided of the sometimes laborious processes that were involved in this work: from locating the original sources of the data to homogenizing the records and eliminating as many of the outliers as possible. Locating the records required exhaustive searches of archives currently held in yearbooks and other sources of the states, countries and smaller regional authorities that existed at various times during the last 200 years. Homogeneity of each record was assessed by comparison with neighbouring series, although this becomes difficult when the density of stations reduces in the earliest years. An additional 47 series were used, but the density of the sites in Austria and Switzerland was reduced to maintain an even coverage in space across the whole of the GAR. We are confident of the series back to 1840, but the quality of data before this date must be considered poorer. Of all of the issues involved in homogenising these data, perhaps the most serious problem is associated with the differences in the height above ground of the precipitation gauges, in particular, the general lowering of gauge heights in the late 19 th century for all countries, with the exception of Italy. The standard gauge height in the early-to-mid 19 th century was 15-30m above the ground, with gauges being generally sited on rooftops. Adjustments to some series of the order of 30-50% are necessary for compatibility with the near-ground location of gauges during much of the 20 th century. Adjustments are sometimes larger in the winter when catching snowfall presents serious problems. Data from mountain top observatories have not been included in this compilation (because of the problem of measuring snowfall), so the highest gauge sites are at elevations of 1600-1900m in high Alpine valley locations. Two subsequent papers will analyse the dataset. The first will compare the series with other large-scale precipitation datasets for this region, while the second will describe the major modes of temporal variability of precipitation totals in different seasons and determine coherent regions of spatial variability.
