I invoked a version 2.4.3 ncdump(1) that I built on the file on Shavano.
Here's the first 3 pages of output:

shavano$ ./ncdump /usr/tmp/lsd/z500
netcdf z500 {

        lat = 73 ;

        chid = 4 ;

Is this what you get when you run Shavano's ncdump(1) on the file or 
are some of above values zero as you previously mentioned?
