High-resolution luminescence speleothem records from Savi Cave, Trieste, NE Italy - We measured three luminescent records from the sample SV1, a stalagmite from Savi Cave (Trieste karst, Italy). The longest panoramic record (having the lowest resolution from the records) is a proxy of the solar infl uence on the climatic system and covers last 14430±176 years. The step of the record varies from 1.1 to 12.7 years. First composite record, which consists of 81000 data points, is compiled of 39 overlapping scans. It covers the last 5005±140 years. The time step of the record varies from 9.9 days to 33.9 days. The highest resolution record covers last 2028±100 years and allows precise determination of growth rate of the stalagmite. It consists of 40106 data points compiled of 16 overlapping scans. Its time step varies from 15.6 days to 19.9 days. We made a reconstruction of the annual growth rate variations for the last 2028 years, which represents annual precipitation for this region.

Abstract
High-resolution luminescence speleothem records from Savi Cave, Trieste, NE Italy - We measured three luminescent records from the sample SV1, a stalagmite from Savi Cave (Trieste karst, Italy). The longest panoramic record (having the lowest resolution from the records) is a proxy of the solar infl uence on the climatic system and covers last 14430±176 years. The step of the record varies from 1.1 to 12.7 years. First composite record, which consists of 81000 data points, is compiled of 39 overlapping scans. It covers the last 5005±140 years. The time step of the record varies from 9.9 days to 33.9 days. The highest resolution record covers last 2028±100 years and allows precise determination of growth rate of the stalagmite. It consists of 40106 data points compiled of 16 overlapping scans. Its time step varies from 15.6 days to 19.9 days. We made a reconstruction of the annual growth rate variations for the last 2028 years, which represents annual precipitation for this region.Pubblicazioni consigliate
