NetCDF to Vis5d via Ferret
This vis5d functionality of Ferret turns out to be a cinch to use -- for example, the following launches a vis5d session with the annual-average temperature field for the world ocean:
setenv PATH :/usr/local/vis5d+/bin ferret yes? use levitus_climatology yes? go vis5d_write temp.v5d temp yes? go vis5d_start temp.v5dThe Ferret developers have written several scripts to interface with vis5d (see /usr/local/ferret/go/vis5d*.jnl). To use these, one needs to append /usr/local/vis5d+/bin to the PATH. We could eliminate this step by adding the following links in /usr/local/bin:
/usr/local/vis5d+/bin/vis5d /usr/local/vis5d+/bin/v5dappendThe shell script that uses Ferret to "convert" a NetCDF file to Vis5d is nc_to_vis5d.
The results are in /home/atw/mytest/vis5d. All the work was done by get_data.jnl, which regrids all the variables to a common grid with even spacing in latitude (apparently Vis5d can't handle irregular y-axes).
