The SUMup database containing over 2,000,000 community observations of snow/firn density on ice sheets, snow accumulation on ice sheets, and snow depth on sea ice is available at the Arctic Data Center. This year we plan to add a 10 meter ice core temperature dataset. We continue to expand this database annually through contributions of field observations from the community. If you would like to submit any measurements of snow/firn density, annual snow accumulation, 10m ice core temperatures, or snow depth on sea ice for the SUMup August 2019 release, please contact or Lynn Montgomery (This email address is being protected from spambots. You need JavaScript enabled to view it.) or Lora Koenig (This email address is being protected from spambots.
