- Abstract
Increasing atmospheric temperatures over ice cover affects surface processes including melt, snowfall and snow density. Here, we present the SUMup dataset, a standardized dataset of Arctic and Antarctic observations of surface mass balance components. The July 2017 SUMup dataset consists of three subdatasets, snow/firn density (doi:10.18739/A26D6F), snow accumulation on land ice (doi:10.18739/A2XX0V), and snow depth on sea ice (doi:10.18739/A22Q35), to monitor change and improve estimates of surface mass balance. The measurements in this dataset were compiled from field notes, papers, technical reports, and digital files. SUMup is a compiled, community-based dataset that can be and has been used to evaluate modeling efforts and remote sensing retrievals. Measurements in the dataset are sporadic in time and have spatial gaps, however, they likely constitute the largest set of field measurements compiled, standardized and publicly available. Analysis of the dataset shows that Greenland ice sheet density measurements in the top 1 m do not show a strong relationship with annual temperature. At Summit Station, Greenland accumulation and surface density measurements vary seasonally with lower values during summer months. The SUMup dataset is a dynamic, living dataset that will be updated and expanded for community use as new measurements are taken and new processes are discovered and quantified.
