Parallel netCDF4 allows first Greenland simulation on a 1km grid

The upcoming stable 0.5 release supports parallel NetCDF4, thus avoiding the file size limitations of netCDF3. This allows for unprecedented grid resolutions.

Here at UAF we have performed the first Greenland 1km 100-year simulations, run in parallel on 512 cores.

Observed and modeled surface speeds in meters per year.

a) observed (Joughin et al., 2010)

b) PISM constant-climate initialization

c) PISM paleo-climate initialization
