Ice and Climate: Regional modelling

 

Greenland

Introduction

Helsen et al., 2013

Over the years, RACMO and the Firn Densification Model (FDM) have been applied over Greenland using different model versions, at different resolutions and with different forcing at the lateral boundaries. Below is a list with executed runs and whether the data are still available. Since the FDM is forced by RACMO data, the data is presented in order of decreasing RACMO versions.
