Glacier data assimilation on an Arctic glacier: Learning from large ensemble twin experiments
Wenxue Cao, Kristoffer Aalstad, Louise S. Schmidt +2
Glacier modeling is crucial for quantifying the evolution of cryospheric processes. At the same time, uncertainties hamper process understanding and predictive accuracy. Here, we s…
