The Greenland Automated Mass Balance and Boundary Layer Experiment (GAMB2LE) is a research project led by the National Centre for Atmospheric Science as part of the Advanced Research + Invention Agency (ARIA) Forecasting Tipping Points programme. GAMB2LE will create a next-generation, modular, scaleable polar observatory capable of characterising the ice-atmosphere interface in remote and under-sampled areas of the Greenland Ice Sheet.
