Annual glaciological survay of italian glaciers

In this paper we present results of the annual glaciological survey (2019) conducted on Italian glaciers. More than 200 volunteers operated in the three Alpine sectors (Piemonte - Valle d'Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group). Data on the frontal variations measured during the 2019 glaciological survey are reported: 102 glaciers were visited in the Piemonte - Valle d'Aosta sector (54 were measured), 24 in the Lombardy Sector (20 measured), 61 in the Triveneto Sector (54 measured) and 1 in the Apennines. Section on mass balance measurements furnishes data for 21 Italian glaciers monitored during the 2018-2019 hydrological year (4 in the Western Alps, 16 in the Eastern Alps and one in the Central Apennines).
