Processing Tools

DOM2NC: You can convert DOMAIN.INFO to netCDF using dom2nc.tar.gz (contributed by Jason Bell). To run dom2nc, untar and unzip the file, make the executable, and then run the executable (see below). You may need to customize the makefile for your compiler and DOMAIN.INFO location. You can then view the netCDF file in the application of your choice (e.g., GrADS, NCL, Ferret, Matlab, NCVIEW).

tar -xvfz dom2nc.tar.gz
