Scripts to builds CISM base data

This is a collection of (mostly python) scripts to build a base dataset for the Community Ice Sheet Model, CISM. The requisite data is not included.

Instructions

First, you will need to link or copy the data into the data directory or edit the file paths on lines 17 through 25. Currently they are set to be:

#==== Data Locations ====
# Link data here or edit 
#========================
lc_bamber   = 'data/BamberDEM/Greenland_bedrock_topography_V3.nc'
lc_mask     = 'data/Ice2Sea/ice2sea_Greenland_geometry_icesheet_mask_Zurich.nc'
lc_massCon  = 'data/IceBridge/Greenland/MCdataset-2014-11-19.nc'
lc_InSAR    = 'data/InSAR/Joughin2015/greenland_vel_mosaic500.nc' #NOTE:  will build this file from mosaicOffsets.* files
lc_racmo2p0 = 'data/RACMO2.0/Racmo2MeanSMB_1961-1990.nc'
lc_seaRise  = 'data/SeaRise/Greenland1km.nc'

Once the data location paths are correct, you can build the datasets by running:

$ python build_greenland_datasets.py

which will take aproximitely 20 minutes to run. It will create a template netCDF4 file called templates/greenland_1km.mcb.nc that has no time dimension. From this file, a set of time-stamped .mcb.nc and .mcb.config files in the complete/ directory are created with an added time dimension for 1, 2, 4, and 8 km spacing over Greenland.

build_greenland_datasets.py also has some optional arguments:

usage: build_greenland_datasets.py [-h] [-v | -q]

optional arguments:
  -h, --help     show this help message and exit
  -v, --verbose  Increase the output verbosity
  -q, --quiet    Run silently

Data:

Each data/*.py file's doc string contains a detailed description of the data.

Authors:

Joseph H. Kennedy reworked scripts by Steven F. Price, Matt Hoffman, and Matt Norman.

The old scripts this package was built off of live in util/old.
