Ice and Climate: Regional modelling

 

Ice Caps

Introduction

With the increase of computer power the number of grid points and thus the horizontal resolution has improved. It now is possible to run RACMO and the Firnd densification model (FDM) over ice caps as well as the ice sheets. 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.
