Today is π-day and NASA's Image of the Day features some information that @HazLovell and I provided (independently). An alternative title that I suggested was "An Ice Pi with Swiss Cheese". earthobservatory.nasa.gov/im…

Just out! Kochtitzky W, Copland L, King M, Hugonnet, M, Jiskoot H, Morlighem M, Millan M, Khan SA, Noël B (2023). "Closing Greenland's mass balance: Frontal ablation of every Greenlandic glacier from 2000 to 2020." Geophysical Research Letters 50. doi.org/10.1029/2023GL104095

Total glacier mass balance consists of two components: climatic-basal mass balance and frontal ablation. Our paper is the first to calculate frontal ablation for entire Greenland and we find that frontal ablation is the dominant mass loss component.

Calculating frontal ablation is complicated and incl. measurements of ice flow (ITS_LIVE & MEaSUREs), margin changes (from Landsat, ASTER, RadarSat), ice thickness (from Operation Icebridge & BedMachine), volume change (geodetic mass balance) & surface mass balance models (RACMO)
