I'm not sure if the string is actually in the title, looking at the
output it seems that the title is just "NRA1 Wind Speed", as it should
be. From a shell command line, you can do

ncdump -h NRA1_WND_6HR_DAILY_1992-2000.nc

to see what attribute the string is stored in. If it's in the title
then it should be in the "long_name" attribute. Once you know the
attribute, you can use (again from a command line) the program ncatted
from the NetCdf Operators toolkit (NCO) to remove or modify the
offending attribute. Something like

ncatted -a annoying_attribute,d,WND,c,""   NRA1_WND_6HR_DAILY_1992-2000.nc

(check the ncatted manual page for more exact information).

Good luck,
