[ncl-talk] NCL wrf_contour use for multiple files

[Bill Ladwig]

Hi Jade,

Can you do an "ncdump -h wrf_file" or an ncl_filedump and report back the
number of times for each file?  With WRF, sometimes the last file has less
times than the other files.  In this case, it might be only 1.  With a
tend_int greater than 1, you might be jumping past the last time.  Without
seeing the data, it's hard to say.

Bill
