[ferret_users] Re: your mail
Hi Nadia,
The /BAD qualifier will not go with the FILE command.
But with the "SET VAR" command. So proceed as follows :
yes? ..............
yes? file/grid=xygrid/var="temp" july_2000.dat
yes? set var/title="Meaningfull title"/units="^oC"/bad=-999 temp
yes? save/file=july-2000.nc/APPEND temp
Always try to give a meaningfull title and units before
writing a variable to NetCDF file.
Hope this helps,
Jaison
