NETCDF_GIS_READ
Read NETCDF Files of GLIMMER GIS Data

NETCDF_GIS_READ is a MATLAB program which reads data from a GLIMMER data file, written in the NETCDF format, containing GIS data.

The GIS data includes dimensions:

• level
• time
• x0
• x1
• y0
• y1

The GIS data includes data arrays:

• acab(x1,y1,time)
• artm(x1,y1,time)
• beta(x0,y0,time)
• bheatflx(x1,y1,time)
• temp(x1,y1,level,time)
• thk(x1,y1,time)
• time(time)
• topg(x1,y1,time)
• x0(x0)
• x1(x1)
• y0(y0)
• y1(y1)

Source Code:

• gis_data_print.m prints the GIS data (usually much too much information!)
• gis_header_print.m prints the GIS header information.
• gis_read.m reads a specified GLIMMER GIS file.

Examples and Tests:

• gis_test.m reads a GLIMMER GIS file and prints the header information.

GIS_5KM.180211 contains data for Greenland at a 5KM resolution.

• gis_5km.180211.nc, the data.
• gis_5km.180211_header.txt, the header information as retrieved by NCDUMP.
• gis_5km.180211_output.txt, the header information as retrieved and printed by running gis_test on the data.
