Aims
Testing the ability of glimmer-cism to predict changes in ice thickness and velocity for Antarctica over the period 1980 to 2004.

Simulating changes in the Antarctic ice sheet for the next 200 years using data from regional climate models for the A1B and E1 SRES scenarios.

A sensitivity study of key model parameters in glimmer-cism will be carried out and I will also help support an ice model inter-comparison project with Tamsin Edwards.

This work forms part of the ice2sea project.

Week ending 13th November 2009
Ran glimmer-cism using the glint driver. Forcing with one year NCEP data repeated for 10 years. Initial conditions 1) Ice surface elevation 5km provided by Anne Le Brocq (5km resolution) and 2)  Bed Topography from BEDMAP1_plus  (5km resolution).

I had to run on the 20km resolution because I encountered a run time error about insufficient virtual memory when I ran on a 5km resolution. Perhaps 5km is too fine a resolution to run the model or I need to look for a bug. Prepared ERA-40 monthly 2m temp and total precipitation data for input into glimmer-cism for the years 1958-2002. Changed the driver to read in ERA-40 data.
