Uncertainty Analysis of Numerical Ice-Sheet Models

Uncertainty Analysis of Numerical Ice-Sheet Models

By utilizing polar ice sheet dynamics models, NIMS performs studies on the melting of polar ice sheet, draining into oceans of meltwater, and their effects on sea level rise in Korean peninsular. In addition, NIMS estimates the sea level rise for every kilometer of the coastline of Korean peninsula and conducts studies to predict the problem of coastlines retreat in coastal waters.

Key Research Content

  • Mathematical comparison and verification of the strong and weak points of ice-sheet dynamics models based on methods of quantifying uncertainty
  • Parameterization of physical processes using deep learning and initialization of ice sheet behavior using inverse problems and data assimilation
  • Development of an ice-sheet separation phenomenon calculating ice-sheet model module that considers oceanic effects
  • Effects of global climate change and the correlations between ice-sheet melting and rising sea-levels
