GlacierMIP Activities/Experiments

Phase 1
A comparison of the glacier volume change projections 2015-2100 from six published modeling studies is currently underway including >250 individual model runs based on 26 GCMs and four emission scenarios. Preliminary results have been presented at several international conferences. A publication is in preparation.

Phase 2
All participating modeling groups will make global-scale glacier volume projections until 2100 based on standardized experiments using the following data and variables:

1) Glacier models will be forced by the following GCMs (provided necessary data  for specific glacier model are available):
1 MPI-ESM-LR
2 GFDL-CM3
3 CanESM2
4 NorESM1-M
5 GISS-ER2-
6 CCSM4
7 CNRM-CM5
8 IPSL-CM5a-LR
9 GFDL - ESM-2M
10 CSIRO-Mk3-6-0

2) GCM runs forced by emission scenarios RCP2.6 and RCP8.5. If more model runs are possible, use RCP4.5 and then RCP6.0 from these models

3) r1i1p1 realizations of the climate models above

4) Glacier inventory RGI6.0. For the Greenland periphery all glaciers with connectivity level 0 and 1 should be computed (level 3 glaciers should be excluded).

5) Standardized initial ice thickness to be provided by Matthias Huss based on RGI6.0

6) Assuming density of ice = 900 kg/m3 for conversion of glacier volume to mass

7) Output will be reported for all RGI primary regions (global projections are targeted including all 19 RGI regions but minimum requirement for participation is the computation of 1 complete RGI region)

8) Assuming ocean area of 362.5 x10^6 km2 (following Cogley et al. 2011) to convert volume change to sea-level equivalent.
