INVESTIGATING THE PERFORMANCE OF A HANDHELD MOBILE MAPPING SYSTEM IN DIFFERENT OUTDOOR SCENARIOS

Paleoclimatic glacial archives in low-latitude mountains are increasingly affected by melt, causing heavy percolation and removing snow and firn accumulated across months, seasons, or even years. Here we present a proxy system model that explicitly accounts for melt in ice and firn cores. Compared to traditional annual layer counting, the model significantly improved the interpretation and annual dating of the Mt Ortles firn core, in the Italian Alps, which includes the very warm summer of 2003.
